How To Treat Stiffness And Soreness In Hip And Pelvic Area Caused Due To An Accident?

I was in a major car accident (hit directly on drivers door at 50mph) about 5mos ago and almost died. The x-rays showed I had a fractured pelvis, pubic bone, and multiple tiny fractures on my right hip and waist, I also had a lot of internal bleeding. I had surgery (over 3hrs) and got and external pelvic ring and pins (11ins long) going through my pelvis, pubic bone and hip bone (on both sides) to align them back up. I wore this 9 and half weeks. I was bed and wheelchair bound for this time. I had to learn to walk again. I have had several PT and OT sessions and I did everything the PT s asked, but before and after each session I was always asked what level (between 1-10 of pain I was in) it was usual a 2,3, or 4. I made it clear that I was stiff and sore most of the day and it was worse after each PT session. I was told in time it would go away, I also try to walk about 2 miles 4 times a week (after my walk I m exhausted) . I was told keep a cane with me and only use it when I really needed it. The last 2mos since the ring has been removed and with PT and walking, I still am stiff and sore and tire easy and I am not sleeping well and ache all over, I have frequent headaches (which I rarely had before the accident) on a daily basis. I am being told this all will pass and it looks like I might have the starting of arthritis. I have been a real trooper and have done everything the Dr, PT, and OT have asked and I am reminded by them how well I am doing. But, they seem to avoid answering my questions about why I am stiff, sore, ache and have frequent headaches. Tylenol doesn t work for me and I don t want to become addicted to pain meds (I was given tramadol) and I only take it when I really can t stand the soreness, aches and pains (I still have over half my pills left) topical rubs and hot showers work for a little while, but not long enough to get through the day without reapplying. I have still not been released to go back to work (I am a stylist and stand most of the day). I am 50 yrs young (as of May) and have a child to raise (single parent).....is this ALL in my head or do I need another opinion. Thanks, Mr. Kel Hedlund
