I have been on Propranolol for about 3 months now. I take 40mg, 3 times a day. I was put on Propranolol for a rapid heart beat....lots of test were done, all confirmed that nothing was wrong with my heart and it was functioning normally. There was speculation that I might have thyroid problem, but after a few blood tests that was also ruled out. I have concluded that my irregular heart beat was from anxiety.
Anyway, ever since I have started on the Propranolol my back seems to be on fire! It's mainly my upper back, most of the time my left shoulder blade hurts the most. However, this pain can raidiate from my lower neck to both shoulders...its different from muscle soreness...it burns and sometimes it feels really deep.
It might not have anything at all to do with my medication, but the reason that I feel there might be a relationship is...After I had my 2nd child I was put on Labetalol (very similiar to Propranolol) for high blood pressure and I had the same sensation in my back. Once I was weaned off of that medication the back pain went away. At that time I attributed my back pain to the fact that I had just given birth and carrying around a baby.
I dont know if there is any relation and I havent spoken to my Dr. about any of this yet (it gets difficult to leave work all the time for appointments between me and my kids), but if anyone can offer any input I would appreciate it!
