Small bumps on arms and legs. Very itchy. No puss. Dry skin. What could it be? No other signs. Allergic reaction or more?

Small bumps on arms and legs. Very itchy. No puss. Dry skin. What could it be? No other signs. Allergic reaction or more?

Probably: An irritative folliculitis...inflammation of the tiny pouches I which your hairs are growing. This is often caused BY SHAVING TOO CLOSE or TOO OFTEN! An antibacterial moisturizing soap may help! Ask your PCP (Primary Care Provider) for a suggestion!
Hope this helps!

See your doctor: Contact reactions generally don't spread ; when they do, they're usually pretty severe and won't respond to creams. You will do best with a course of oral steroids from your doctor ...Read more

I have had severe upper rhespiratory problems due to allergies for the past few days but today they re better but now after taking a Claritin and a hot shower I have a blotchy red rash on my arms and legs it s not itchy but I m wondering what the cause mi

Viral? Allergic?: Blotchy appearing reddish rashes can occur when the blood flow in the tiny vessels at the skin's surface change, such as in an allergic rash, a viral rash, or in reaction to changes in skin temperature. Viral infections that cause cold symptoms and other symptoms can sometimes cause such skin patterns (fifth disease, caused by a virus, can cause reddish patterns). A doctor can evaluate if needed. ...Read more

Past three days been extremely itchy all over body, primarily arms and legs. No rashes, etc. No new changes at all. No allergies. What can be cause?

Past three days been extremely itchy all over body, primarily arms and legs. No rashes, etc. No new changes at all. No allergies. What can be cause?

May be hard to find: About 50 % of cases of itching without rash, one is not able to figure out the cause. Of course, the common allergens are something inhaled that the histamines in the body react to; or some new perfume or scented lotion, deodorant or something else new used on skin. Suggest taking an otc antihistamine daily, take only lukewarm showers. Will likely go away in 2-3 weeks. If not, the usual: c the doc. ...Read more

Depends: You may try taking otc antihistamines like claritin, (loratadine) zyrtec or allegra. You may also try 1% Hydrocortisone cream sparingly on your rash. Try to avoid scratching as much as possible. If these measures do not help, seek your doctor's help. ...Read more

I feel dizzy, my legs, arms and tummy area feel itchy? Maybe it's some sort of allergic reaction?

See your doctor!: Although itching can be due to an allergic reaction, it could also be due to many other causes. Your doctor will need to take a careful history and exam you in order to identify the cause. Also, dizzyness along with itching could be an early sign of a severe allergic reaction. ...Read more

Large painful bite looking bump on side of neck, allergic reaction to bandaid covering it, now rash around neck, chest, legs, and arms. Very itchy!

Large painful bite looking bump on side of neck, allergic reaction to bandaid covering it, now rash around neck, chest, legs, and arms. Very itchy!

Mgt suggestions: From your description, the area on the side of the neck may be an insect bite, and the total body rash part of an allergic reaction.Exam the neck area for any bite marks, stingers. I would suggest not attempting to remove the stinger. Applying Hydrocortisone and Calamine in combination with an antihistamine may provide relief.
I agree that if you have any breathing problems, proceed to the ED. ...Read more

Hi I took venalfaxine was fine when took 1st one but when took 2en one my arms nd legs went number throat felt like was closein up but it wasn't panic attack or allergic reaction I had them before years ago?

Need examination: If a precipitous event as you describe is NOT allergic then, the event is likely not due to the medication either. I believe a bit more history on how symptoms evolved and subsided would help. Could there've been an interaction with another drug you're taking? Call your doctor about this as well.

I believe I'm having an allergic reaction to something I ate yesterday. I had sushi for the first time and now my body is covered in hives all over, including my legs, chest, stomach, neck and arms. I took two Benadryl yesterday and they cleared up but no

Sushi: Allergy or any seafood allergy is common, even if you ate it before, sushi and other eastern seafood contain many unknown ingredients, better to avoid eating it again, keep an antihistaminic as cetirizine or loratadine handy case you develop a reaction again, be cautious when eating food with unknown ingredients, you might want to see an allergist if the problem continues, check aaaai.

I got my 1st HPV in Dec of 2010 which I had no reaction to. I didn't get my second one until Oct of 2013. I had tingling in my arms and legs after that one for 2 weeks and my gyno said don't get the 3rd but im scared im at risk only getting two?

OK to re-vaccinate: It is unlikely the tingling was a vaccine side effect; I think your gynecologist was being unnecessarily cautious. You still need 2 more doses and maybe 3. Back in 2010, the vaccine covers only 4 HPV types; but in 2013, it could have been either Gardasil-4 or Gardasil-9. Nowadays, only G-9 is available; you need a total of 3 G-9 doses. ...Read more

I have been on sulfamerh/trimethoprim for 17 days. Have been off for 3 days now I have a wierd rash on my arms and legs can this be a penn. Reaction?

Maybe Med Reaction: Trimethorprim/ sulfamethoxazole is a sulfa based antiobiitic. Not a penicillin derivative. That said it is still a common source of allergy. Talk to your doc. It may very well be the drug. If your having any breathing difficulty go directly to your nearest er. ...Read more

Have been treating entire body for fungal infection with coconut oil rash gone skin dry and flaky now still itches really bad possible I'd reaction? Symmetrical rash started on torso spread to arms and legs has reached ankles still extremely itchy on breas

Sounds fungal: Would need more background information as there are several potential causes for rash such as this. However, ruling out fungal infection is at top of list. Coconut oil has good antimicrobial properties and may have helped calm an inflammatory reaction to the infection, but does not seem to have completed the task. Would see a physician to confirm and take antifungal medication. ...Read more

Last night I ate 2 pcs of chicken and develop some rashes in my arms and legs, can I consider it as one of d foods tat im allergic with?

Not yet: Symptoms such as rash after exposure to something like food may be due to an allergy, but there are multiple things, both allergic and non allergic, that can cause a rash. Food allergy is just one and can be serious if that is the cause. I recommend seeing a board certified allergist for an evaluation and testing. ...Read more

Red, raised, rash on arms and legs, allergic raction from Depo-Provera provera (medroxyprogesterone) shot?

Reaction to Depo: Can happen, usually due to the carrier the progestin is in, but could also be the progestin itself. Unfortunately, once you get the shot, you are along for the ride. Allergy treatment is about the best you can do, usually using an anti-histamine. A natural approach is quercitin, a natural antihistamine found in the skin of red apples. ...Read more

ER doctor prescribed me Keflex for possible mastitis and UTI knowing I'm allergic to penicillin. I am on day 3 and have an itchy rash on arms and legs?

Possibly allergic: Cephalexin (Keflex) and related antibiotics (the cephalosporin group) are chemically similar to penicillinl. Although penicillin allergic persons usually can take them without problem, occasional cross reactions occur -- i.e. you may be allergic to the cephalexin. Check with the doctor who prescribed it. ...Read more

If both of the entire hands and feet are numb, then a peripheral neuropathy is more likely. This can be related to long standing diabetes.
