Welcome @follest, It must be extremely frustrating having the symptoms/pain go away only to come back with a vengeance. I wasn't familiar with post surgical inflammatory neuropathy so did a little research and listened to this 2010 Mayo Clinic video on the topic. It does sound like what you have described.

I did a search of Connect for "post surgery inflammatory neuropathy" and found a few members who have commented on the topic. I thought it might be helpful to look through their comments while you wait for members with experience to respond. Here's the link to the search results - https://connect.mayoclinic.org/search/comments/?search=post%20surgery%20inflammatory%20neuropathy.

Have you discussed your thoughts on the possibility of post surgical inflammatory neuropathy and treatments that might help with the surgeon or your primary care team?
