Itchy Rash

Hi, I have an itchy skin rash that I've had for about a month and it is in random places on my body; the sides of my stomach, my back, thigh, butt, knee and now spreading to my genitals. Some of the bumps are big, some little, I even just noticed small bumps on 4 small bumps on my palm. I even took an std exam and everything came out negative, the HIV test is the only one I haven't gotten back yet. I don't know what it is, the itchy rash is the only symptoms that I have, I think some bumps might have gotten big due to scratching a lot, and I also take really hot showers it helps relieve the itching but I'm not sure if it's bad for it... I could use some professional help

Hello,
From the symptoms the possibilities of an allergic reaction, viral rash, eczema and hives need to be ruled out. Hives (medically known as urticaria) are red, itchy, raised areas of skin that appear in varying shapes and sizes. They have a tendency to change size rapidly and to move around, disappearing in one place and reappearing in other places, often in a matter of hours.
To confirm the diagnosis and the allergens if you are allergic to any of them, I would suggest you to get it evaluated from a dermatologist.

It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your doctor. I sincerely hope that helps. Take care and please do keep me posted on how you are doing.
