In a previous post, I explained that I developed a sudden bout of sciatica. I am a healthy, active, fitness-enthusiast. I am a 56 year old female who has never experienced back pain. As is my nature, I am a worrier and have been doing a lot of research. I have had 3 sessions of PT. My PT seems very knowledgeable and he feels that my problem may be more mechanical/structural vs a disc issue (I have a natural exaggerated arch in my back and I have been doing the same exercises and movements for a long time....so stressing the joints in the same manner). Of course I have seen that tumors and cancers are other possibilities for this type of pain. My symptoms (left buttock/quadriceps pain and spasms along with left knee pain) have been occurring for one month. I am certainly better than I was the first week of onset, but the symptoms do continue. My insurance will not cover an MRI without additional treatment/PT. I have also read that MRIs for sciatica are not necessarily recommended or beneficial. I know that sciatica can last a long time and that the course greatly varies for each individual. Just looking for reassurance that this is a somewhat normal course. Does anyone have increased symptoms after PT? I feel as though I will never get better! Thanks so much for listening to my concerns!
