Does having a shower make anyone else cry?

I really can’t bear the feel of running water down my left side, including my head, and it is making showering really difficult (even more so because of balance problems too). It makes me cry every time as it sends neurological surges up and down my body. Is this common and has anyone found anything to alleviate it? I am already on max dose gabapentin but don’t feel like it is doing anything.
