One of my students what diagnosed with scabies. I have developed a red rash on my legs but it is flat and not little bumps. It does not itch it burns.

Unlikely scabies: It is unlikely that you were infected with scabies in a normal classroom situation. You would have to be in physical contact for the scabies to transfer from person to person, or clothes to clothes. Scabies is also very itchy usually, so if your rash doesn't itch it is even less likely to be scabies. If you have recently shaved your legs it may be folliculitis, but only an exam can tell. ...Read more

4-5 LITERS???: You do not need to drown yourself. "Viral fever" is so vague as to be a nearly useless diagnosis. Rash on arms and legs may---- or may not---- be viral. How do you know your fever is viral? You should at least apply a lubricating cream, and probably a cortisone cream. There is no point to excessive water consumption. ...Read more

I've been having this odd red rash on my legs that stings when it shows up. Been coming and going for years along with red dots. Can it be eczema?

Could be many things: Eczema, contact dermatitis, or even shingles, if you had chicken pox as a child. However, shingles would be rare in an adolescent with a normal immune system. Try switching to a hypoallergenic laundry detergent and bathe with hypoallergenic soaps. Patients with eczema have higher sensitivity to allergens. See a dermatologist if simple prevention does not help. ...Read more

I have a red rash on the back of my leg and it itches really bad?

Leg itch: A natural question would be to ask if you came in contact with Poison Ivy or Poison Oak. In any event, if the rash is not spreading you can try Lotrisone (clotrimazole and betamethasone) creme which is over-the-counter. This should help to clear it up. If the rash is spreading you should probably see a Dermatologist. ...Read more

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

Dr, I have severe itching in leg with red rashes for last two days & reduces on Avil tab. 'M on warf 6mg & HCQ 400. Is it medicine's allergy?

Probably not: But you need to talk to your doctor about this issue. Warfarin rash tends to induce huge bruises and likely more generalized than confined to the legs. However, it is possible that this may be from HCQ especially if it had been introduced within the past month or so. If problem persists, you may need to see a dermatologist. If it is helped by Advil, (ibuprofen) I would look for the presence of vasculitis. ...Read more

I have small, painful rashes on my back and legs. My eyes are red and I have swelling everywhere. What is happening?

Insect allergy?: Good morning, painful rash on back and legs can be due to many causes. One patient developed such a rash after staying in a hotel; my diagnosis was bed-bug-allergy, as the rash was limited to the back of trunk, and back of legs, and the protected areas such as those covered by intimate clothing was not affected. Since your eyes are red and swelling everywhere other causes of need consideration. ...Read more
