I would ask the doctor about the above possibilities, and then focus on things that can be done for venous insufficiency if that is the diagnosis. However, if she has not had the above tests, I would. For the last six months I have had severe pain all the time from my left hip and back of my leg. I only get about four hours of sleep a night because of the pain in the whole left side of my leg, hip and left foot. I'm not quite sure what your question is.
Physical therapy is also of help.
If there is no change, or if the physical shows severe nerve involvement, a CT of the lumbar spine and nerve conduction tests may be necessary. About 3 months ago I went out jogging with some friend for about 3 miles. This is the first time I have ever jogged this far in my life. I thought I had just twisted it and forgot about it. There was no other pain.
