I would call the doc who prescribed it. You want to make sure it doesn't mix with the other meds. I have a friend who takes it to calm her anxiety when needed I think. Its better to be safe then sorry though so call your doc. I'm a little confuse by your post. Now do you feel like you have anger issues and that makes your pain rise? So maybe finding a med to assist with your mood levels. Can you tell me more about your glucose intolerance? I had blood work which said I'm not but between my pain,stomach and out of it I often felt I am. Its interesting how you said you could see the pain difference.
On the treadmill issue. Maybe you did do something or maybe you just strained from overuse. That is a long time. Again is there a doc you could call? See with our issues sometimes its hard to know if its a nerve or muscle or bone or maybe a combo or different at each time. I know from my issues the treatment around rest is different for all. Sorry not too many answers for you.
