I don't know if you are an allergic type or not, but what you are describing sounds exactly like dyshydrotic eczema. It is a rash of tiny blisters usually on the palms and soles of feet. They happen often after intense exposure to water, and perhaps a chemical in the water, seems to be the culprit most of the time. The treatment is try to figure out what caused it and eliminate it. Also steroid creams and Zytrtec or claritin otc for the itch.
Here is an article and classic pic of the blisters (top pic):
These are a little bigger than usual...
We treat basic cases with topical steroid creams- topicort,synalar, triamcinolone, betamethasone etc. and removal of the trigger if one can figure it out!
Make an appt with your doc to get an RX, & you will be on your way!!
Good luck and be well-
OK- so they are on the back of your hands....
And look like tiny bumps or blisters?
Only hands involved?
Anything on feet or inside mouth?
How long has this been going on?]
Have you been sick otherwise?
Given all this- I think you should be seen by a doc.
The blisters on hands, mouth ...and if feet as well can be a common virus we see most often in kids- called Hand, Foot and Mouth Disease- it is a virus and goes away all by itself.
But w. vag pain and painful urination, you need an exam and urinalysis.
He can only give you genital herpes via oral sex if he gets cold sores and has one now..... But if your sex is unprotected, you probably have been exposed anyhow, right?
The blisters on the hands should be looked at- given your Immune deficiency, that opens the door to many bugs. Although the things that cause this are the dyshidrosis I mentioned previously (palm doesn't have to be involved) and scabies, which would itch intensely and spread, and not come and go.
All in all--- with the IgG issue, I don't feel comfortable making a possible stab at what is going on beyond this. Chlamydia can be passed back and forth, and can do a lot of internal damage to you- so you need to go get checked and tested anyhow.
And- with all these STDs, I hope you have been HIV tested as well. Regularly.
GO see a doc. Today!
Any other questions I will do my best- but you have too many variables that could cause big problems for you- and in this kind of forum, we can't test you or examine you, and that is what you need most.
and do the safe thing and see your doc.
My best and warm regards---
