Thank you for taking the time to respond. I can tell you that pre-surgery, for at least a year, my sleep was regularly interrupted by pain going down my right leg. I used yoga moves to calm it down but that takes time so sleep suffers. Now, post-surgery and without the constant pain, just the stitches healing, I can sleep but I have to let anxiety settle down. When I wake up it is with pretty intense anxiety that I try to keep at bay by doing physical things which helps.
I do have a history of depression but I have been on maintenance medication for some years now without problem. I am still taking venlafaxine and bupropion daily but now it seems to have no impact. That part is puzzling. I spoke to my psychiatrist and he said that since it started up unexpectedly, that it might be related to the surgery and to give it a few weeks to see if it subsides.
Long explanation but more comprehensive. Any thoughts?
