Gabapentin is a anticonvulsant which is also used for nerve pain. Lyrica is as well used for nerve pain. I took it prior to my TKR for pain in my neck but went off due to taking pain meds after surgery but started it back when I started having those Nerve issues when they were coming back to life in my leg. Nerve zaps are a real thing. It also helps with neuropathy due to issues as well if you experience any of that. The sensitive skin does get better as the healing process takes place but being so early in your recovery it may still be sensitive. I am now wearing jeans again and sometimes if my knee is sore I have a compression sleeve that I wear over my thigh/knee/calf area that helps immensely.
