@maggie1960 I’m sure that like me, you’ve been tweaking and tweaking your routines to hone in on what seems to help/hurt you. I want to add that I never had such long discomfort after a shower as you have, mine would only be 90 minutes maybe after a hot shower, but after seeing the benefits of having water lukewarm, I also found that what helped me was taking my shower BEFORE a dose of Gabapentin was due. In my non-shower state, by body knows when my next dose is due, so if I cycle the shower to get that discomfort started before dose time, I found the Gabapentin worked to tackle it along with normal neuropathy pain. But with you having 36 hrs of discomfort after shower, I guess you get several doses of Gabapentin afterward.
Might I add re: nerve conduction study, I must say that after about 8 of them from 5 different Neurologists or hospitals, I do not recall any of them ever giving me advance instructions, especially re: shower beforehand. Because I’m a “bleeder”, I’m sure I always shaved my legs a day before, which would just be my choice to do that of course, as men are not required to shave their legs for it. They wipe, or give you a wipe, if needed to clean your legs, and you can easily apply lotion afterward. That has been my experiences anyway, every doctor is different, but maybe you can push on that if it’s a deal breaker for a test if you think it would be helpful. Hugs!!! This is so tough, Debbie
