I'm not sure how to you help you. Do you have access to a cardiologist?
yes they did all the test and it came back good but my puse was130
I know there is a connection with pain medication and a high pulse rate but I wouldn't be able to tell ya much more than that. Try and stay away from the pain meds though. I have 4 hearniated discs so I know all about back pain. They pushed vicodin and other things for me, I know they help but I didn't want to be on long term pain meds. I do a lot of stretching and strengthening exercises for my back and it's a little bit better. It's tolerable that's all that matters
Good luck.
