I am a 52 year old female, maybe 10 to 15 pounds over ideal weight, not as active as I should be, but I do stand on my feet for 8-9 hours a day, continuous, at work. I also was having deep, dull, hip pain that was not alliviated by pain medicine, and would transfer from one hip to the other when I turned over in bed. I read many of the pages of comments here and so many of them were similar to my own experience. My pain was usually between 2 and 6pm; I am usually getting up at 5 or 6pm. I first experienced the pain last spring and thought it was arthritis, I have arthritis in other areas but the pain from those areas is usually worse in cold or rainy weather. It was spring and getting warm so I couldn't understand it. We went on vacation the first of August and I hadn't had the pain since then until night before last. Some of the posts here were from people who were runners. To make a long story shorter, I narrowed my activity down to a walk on the tredmill. That day was the first time I had been on the tredmill since before our vacation. Day before last and last spring I had been walking on the tredmill about 30 minutes, 20 of it with the incline graduated all the way up, for 4-5 days a week. So to test the theory I did not walk on the tredmill yesterday and NO pain last night. I am going to test the theory further and see if I can walk level without pain. I am not sure what this means as far as the root cause of the pain, sciatica? But, now I know the cause and can stop the pain. I do not have medical insurance so multiple visits to the doctor are out of the question and honestly don't appear to have helped many here. Thanks to everyone who posted here. This is a very helpful site!
