I tore a muscle in my lower back two weeks ago when I bent over to pet my dog. I have atrial fib and some stomach problems. I am not overweight (5'6" 118 lbs). The place where I heard and felt the immediate pain when I tore/hurt the area had a stabbing pain when it happened and continues to have a stabbing pain when I bend over. I finally was able to go see the physician assistant in my doctor's office. She prescribed Bactofen. I currently take Pradaxa, Metoprolol Tartrate (sp?), Omeprazole (stomach/esophagus problem) and vitamins. For the pain, I take Tylenol (I cannot take Aleve, which works best, because of the potential bleeding problem). Question: Is Baclofen the correct med and is it OK with my other meds? Thank you!
