Muscle/joint pain... scar tissue???!!

Hello, I was banded 2 yrs ago and haven't had any major problems with my band. I have not 'followed band rules' for about 6 months now. I've gained back 15lbs. As for my problem/question... I started having pain in my legs, actually the muscles in the backs of my thighs about 2 months ago. [i don't have any lower back issues and haven't exercised in quite awhile.] When I bend over it feels like my thigh muscles are tied in knots. After about 2 weeks of this I then woke up with a severe stiff neck. I had to turn my whole torso to look around. My shoulders, collar bone and down my left arm hurts. It also hurts under my left shoulder blade and it feels like my spine is bruised in that area. I can't raise my left arm fully and hurts like hell when I try. It actually hurts in the 'socket'. My hip joints are so sore that I have trouble walking. I used to walk super fast, always did, but now I look like an old woman when I 'shuffle'. I went to my chiroprator about 6 times and it didn't help.

I just spent 4 days in the hospital and had scans on my neck and brain and blood work out the wazoo all came back fine. I go to a neurologist[?] on monday and they're talking about doing a spinal tap!!

Has anyone had these types of pain and found out it was from scar tissue from their band? I will crap if my band is the cause of all this!! Any help would be greatly appreciated, Darlene
