Dear Anasilva63,
Thank you for your direct question. Unfortunately, without actually examining you or seeing photos of the rash, it is nearly impossible to make an accurate diagnosis or recommend a therapy for you.

There are a few possibilities that you may want to consider and discuss with your doctor--sometimes patients may develop acute hives from a viral infection that can be extremely itchy all over. This is called Urticaria and the cause is often unknown. Sometimes, folks get a very itchy rash from something called contact dermatitis (a classic example is poison ivy) where the source is some substance like a chemical or metal like Nickel that causes a delayed but long-lasting reaction on the skin. Insect bites (i.e. from mosquitos) could cause severe itching depending on how many you might have and where they are. There are some viral infections like chicken pox, herpes viruses, etc, that can also cause itching and also burning and last for days to weeks.

Tingling and needle-like sensations suggest maybe a neuropathic cause or another underlying condition that may be more than just a skin condition. For example, patients who have normal skin and no rash may have extreme itching or "tingling" of the skin as a manifestation of iron deficiency.

My recommendation for you would be to have you primary care physician have a close look at the rash. If it is an obvious diagnosis, they will offer treatment that can provide a lot of relief. If it is unclear, they may refer you to a dermatologist or allergist.

I hope this helps.
Best of luck,
ML
