Hi Cat1234- want you to know I just registered with this forum just so that I could respond to your recent posts regarding next steps...
Based on your comments, I suspect one of two possibilities- fibromyalgia, or- believe it or not, a side affect of the tramadol.

I suffer from fibromyalgia, and a host of other fun things, and can tell you that the pain you are describing is dead on. I suggest you seek an experienced rheumatologist to explore this possibility.

The other thought that occurred to me involves a recent experience I had with tramadol that was prescribed for a nerve disease I have. At first I felt the tramadol was helping...then over time, I started to develop excruciating pain in my neck and back. I thought I was having a serious fibro flare, then came to realize that the back and neck pain was a side effect of muscle spasms being caused by the tramadol. BTW, I am on linzess too and don't feel that is the problem.

Hope this offers some insight and potential next steps,

Holly
