Possible Water Allergy??

For about a year now i have been having some Red Patchy Itchy Rash after, showering, swimming, or any exposure to water for 5 or more minutes. The Rash will usually subside within 2 hours after being out of the water. It is very much a hive like rash all over my body. I have seen 3 different dermatologists and now 2 different allergists, I feel like there are no real answers i was recently told i may have Urticaria (Chronic Hives). I am not sure what else to think or do about this but im not sure  how much more i can deal with.

Also, Routine blood work has been performed and always seems to come back normal except for a Vitamin D deficiency that i am having with a level of 17.

Please look at these pictures and tell me what you think.

Hi, from your history it is clear that you having allergy to water or its contents. Very less has been known about water allergy and it is termed as Aquagenic urticaria. It can be due to exposure to allergens present in water in your area or due to ions in non-distilled water.

If you are allergic to water following measures will help you-
- Stay away from water as long as possible.
- Avoid going in rain outside.
- Keep yourself cool during summer as even sweating will cause reaction.
- Try boiling water before bath and as well can try hot water bath. Avoid showers.
- Dry yourself immediately as soon you finish your bath.  

I hope this will help you. Take care and regards.
