I have a heat rash on my right hand and was wondering if antihistamines would help or if not what is the best way to treat it?

Unknown rash on hand: Not sure what you mean by a heat rash. Other than hives and urticaria I don't know of a rash that will benefit much from antihistamines. You may need to get someone to take a look and make a diagnosis to choose an effective therapy. Make an appointment with a physician if it is chronic or recurrent. If it is mild consider a topical Hydrocortisone cream otc.

Viral: Illnesses can do this. Herpes can cause blisters. Chickenpox, coxsackie, and other viruses can all lead to blisters. If these have been ruled out, great! If it is getting worse then see a dermatologist. Otherwise many rashes just run their course.

Recurring heat rash in cold weather. Causes?

Recurring heat rash in cold weather. Causes?

Not likely heat rash: If your rash is occurring in cold weather, that is not likely heat rash. The term heat-rash refers to a rash occurring due to excessive heat. Eczema is often worse in cold and dry weather and so you may want to have it checked out. Without knowing what the rash looks like and its distribution on the body, it is difficult to make a diagnosis. So, consult doc. Good luck.

How come I have a constant heat rash?

Uncommon: Heat rash should resolve with cooling of the skin and after the sweat glands "calm down". It is caused by blockage of the glands and resultant swelling and inflammation. Your "heat rash" could be something else entirely and I recommend you have it evaluated by a physician.
