Dear Lisa, Its a long time since your original post but.....if you are still struggling i wanted to share some thoughts. I also have a high heart rate same bpm and chronic pain sufferers often have that. With all those meds and no relief I think a visit to a pain clinic is in order. Never heard of Cymbalta being given for nerve pain. Its hard on your liver. I am on some of the same meds for pain and spasticity - 2mg of tizantidine 2x per day,40 baclofen,40 oxy,but i have hit a wall and even botox injections don't help so i did baclofen pump trial-it worked. Thats my next step and you may want to look into that

Hope you find relief!
