Hello,
It is very difficult to make a diagnosis without examination but some of the possibilities for your symptoms are aquagenic urticaria, dry skin (xerosis), psoriasis or dermatitis.Systemic diseases like like liver and kidney disorders,diabetes, iron deficiency anemia can also cause itchy skin.
Water urticaria, or aquagenic urticaria, is a rare condition in which hives develop within 1 to 15 minutes after contact with water. The hives last for 10 to 120 minutes and do not seem to be caused by histamine release like the other physical hives. Most investigators believe that this condition is actually exquisite skin sensitivity to additives in the water such as chlorine but distilled water can also cause this reaction.
It is diagnosed by applying tap water and distilled water to the skin and observing the reaction. Treatment of water urticaria includes epinephrine, antihistamines, or cortisone-like drugs. Itching can be controlled with cold packs or commercial topical agents that contain menthol, camphor, eucalyptus oil, aloe, antihistamines, or cortisone preparations.

I feel that an examination by a dermatologist is required to confirm a diagnosis.
Hope it helps.Take care and pls do keep me posted on how you are doing.
Hello, i want you to know that im only 15 years old. and obviously not a docter , but it sounds like Aquagenic pruritus which is a skin disease that is usually evoked by the contact of water. i have seen many people talk about these types of things, so i recomend you go to your dermotologist and ask about it. i hear some people get on certain meds and iron to help BUT EVERONE IS DIFFERENT. so Consult your Dermotologist FIRST. i hoped i helped. please let me know if i did or not.
Sincerly
