Beta Blockers, Spine pain...any input?

[Kavbear]

I have started taking Nadolol and every night when I take it my spine feels like someone is "wringing it out".  I brought this up to my Cardiologist (this one seems to have promise too after so many fails) and talked to the pharmacist and both said this medication doesn't cause spine pain.  
I have lower back and leg pain because of a car accident but this is different and happens every night with in 30 minutes of taking the pill, so everyone is saying it must be from the accident or fibromyalgia but I don't think it is a coincidence that it started when I started this medication.
It is so bad it keeps me up for hours past when I want to attempt sleeping and leaves me exhausted and wanting to sleep in the morning.
The flip side is it is the first drug that has brought my heart rate down (I have tried two others and one did nothing and the other made me unable to stay awake at all)
I know I can't just "stop" the drug without risking my pulse and BP going crazy (made that mistake with the last one after the last cardio said I could just stop it) but if I could even skip one night and my spine did not hurt then I would know if it was this medication. I'm temped to try it and see what happens, but I am not sure if my "worse case" thought of my pulse and bp go a bit nutty and I have to take a ER trip to get IV's is actually "worse case"....
This journey has taught me my body often does not respond to meds like it does other people.
So frustrated......

Thanks I haven't thought about it that way........I haven't found a local neuro. who knows squat about AD but I am going to push the cardio or my internist to see what we can do.

I don't think the medication causes spine pain, but perhaps it is causing something else that is triggering the spine pain? It's possible that the pain is indeed from fibromyalgia or the accident... it's just being triggered by something the medicine is doing. Perhaps when the effect kicks in, I mean, it *is* blocking a nerve receptor, perhaps that is triggering the thing that triggers the spine pain...

I think a neurologist may be more able to pin the problem there. It's not a primary effect of the medicine, maybe, but a secondary one, perhaps. Maybe worth looking into?
