I've been diagnosed with frozen shoulder, or Adhesive Capsulitis. I've been taking Vicodin every 6 hrs. for the last 4 days, still cannot move my arm/shoulder, and am in a great deal of pain. Does it really take months to get over this? I am in good physical condition, exercise regularly, etc., and did not injure myself. Doctor says they don't know what causes it, but I am going nuts; can't do anything with my right arm, and there is so much pain, the drugs hardly touch it. I'd like to hear from someone who has had a similar experience.
