A.V.
I am so sorry to hear about some one so young with shingles. It is the worst pain I've ever had and I have delivered two babies with no drugs. I have had shingles eight times so I'm a bit of a special case too. The best treatment for pain is litacane patches, and HydroxyPAM an anti anxiety/histamine pill helps me get to sleep at night. The best advice I can give is if he is complaining all the time about the pain please summon extra patients and console him chances are it really is that bad even if you have done every thing the doctors have suggested.
If you have any questions let me know, I have a lot of hands on experience with shingles.
Best wishes for a speedy recovery!
A.
