Hello @carolep80, Welcome to Connect. I also can't stand or walk for too long but fortunately I don't have the pain with my neuropathy, just some numbness. There is another discussion where members have discussed epidurals that might be helpful:

While you are waiting for members with experience to respond, here's a search of Connect showing discussions and comments from members on your Lyrica or Cymbalta question - https://connect.mayoclinic.org/search/comments/?search=lyrica%20or%20cymbalta

You mentioned a pinched nerve is the source of your symptoms. There is discussion started by @jenniferhunter for Myofascial Release Therapy that you might find helpful - https://connect.mayoclinic.org/discussion/myofascial-release-therapy-mfr-for-treating-compression-and-pain/

Has your doctor mentioned surgery as an option?
