Is it possible to develop a skin rash just from dry skin or are skin rashes caused by allergies?

Is it possible to develop a skin rash just from dry skin or are skin rashes caused by allergies?

Yes: and in the case of dry skin, one may see small raised bumps especially at the extremities. These will often be prevented by using a moisturizer with 3 minutes after bathing. A rash can also be induced by scratching as well. Some skin rashes are caused by allergies (often contact, drug etc) while many are not. ...Read more

I have allergy, probably to Ponstan 500. The skin rash is nearly gone after 5 days, but now I start to have really bad rashes. What should I do?

I have allergy, probably to Ponstan 500. The skin rash is nearly gone after 5 days, but now I start to have really bad rashes. What should I do?

Something else?: If the rash improved without treatment only to return a few days after (your dates were not defined), then the problem may be from something other than the drug implicated. If the rash was treated and returned after the treatment was stopped, then the rash (if due to the drug) may last for 2-3 weeks. ...Read more

I have an allergic skin rash. Can hay fever give rashes?

I have an allergic skin rash.  Can hay fever give rashes?

Usually not: "hay fever" refers to the sneezing, itching and nasal congestion of allergic reactions to pollens, most commonly to the weed pollens and molds that are common during the time of year that hay is being harvested. Only in the most exquisitely allergic do these reactions cause rashes. Allergic rashes are very difficult to diagnose; see an allergist or dermatologist for help with this. ...Read more

If well, wait: If the child is otherwise well, has not been on medication, is eating and drinking and playing, wait. It most likely is a viral exanthem (rash). Benadryl (diphenhydramine) is useless against viral rashes or viral infections. Is the child itchy or showing signs of an allergic reaction? Those would be uses for Benadryl (diphenhydramine) or other antihistamine. ...Read more

Rash lining and inside lips; started with itching, turned to burning later on.. I have started using the vasoline and it is working wonderful, but I wanted to find out if this is most likely a skin contact rash or something ingested?

Rash lining and inside lips; started with itching, turned to burning later on.. I have started using the vasoline and it is working wonderful,  but I wanted to find out if this is most likely a skin contact rash or something ingested?

Could be either one: What you describe could come from contact with a substance, like lip product, that you came in contact with. You may be allergic to one of the components. It is also possible that you had an allergic reaction to something you ate. Try to look back over the time just before you got the rash and figure out what it might have been. It does not sound like herpes if burning went away quickly. ...Read more

I have a rash on the corona of my penis and the head. I've been treating as a yeast infection I was just wondering what arevthe signs of the treatment working?

Rash goes away.: If the medicine works, the rash will go away, usually within 10 days. If you have not seen any improvement after three to five days, get seen by a doctor to be sure you do have a fungal infection. There are other causes of rashes besides yeast. If you have had unprotected sex, get checked for std's. Also, avoid scented products and harsh soaps/detergents/fabric softeners. Don't over-scrub. ...Read more

Nystatin dr gave me  is not working for my daughters yeast rash now it looks like she is getting a diaper rash her skin in areas looks scaley  and red?

See a pediatric derm: Diaper rashes are quite common, however there can be multiple causes. Often, it is first treated for yeast, however there is usually a irritant component that needs treatment as well. Infantile psoriasis can show up as a diaper rash, so if it is stubborn and persistent, this can be the cause. Lastly, rare conditions only a pedi derm would be familiar with would be evaluated. Good luck! ...Read more

I have a rash all over if you rub on it you can feel a bumps under the skin.  It itches what can this be?

??Hives??: Sounds like hives with possibly some angioedema (swelling within the dermis). Also known as urticaria. Try a simple antihistamine to see if this helps, if not, you should have someone look at the rash since this isn't the place to diagnose a rash. Needs to be visualized. ...Read more
