I had been taking the 10-235 on and off for the past year or more with no issue for severe thoracic pain. I then developed L3/L4 issues for which I had surgery 3 mos ago. I was up to 4 or 5 a day for the past 4 mos. I was to have a nerve block done 3 weeks ago but had a darn fever so they didn't do it. I am scheduled for this Wed. However, my Doc, through the nurse, refused to refill my script without coming in !!! I'm out and have been for 2 1/2 days. Yesterday I had chills then I was hot. I was also irritated. I couldn't sleep last night and I've been had more anxiety over my injuries and the feeling of doom with crying. I've never been addicted to anything in my life with the exception of smoking and I'm a 58 year old male. Are the listed items symptoms of withdrawal from Norcol? How can I best get through it because I do not plan to take anything going forward if I can help it.
