Thanks for the question. First, let me congratulate you on feeling better. It sounds like you ve put a lot of effort into getting better and you should feel good about yourself. There are a lot of potential causes of the back, hip, and leg pain you describe. If you were in a hospital bed for a long time while recovering, often this alone can cause these types of pain. If you remain physically active, this pain should go away with time. Treatments include physical therapy, and simple over the counter painkillers such as acetaminophen and ibuprofen. If this doesn t help, I recommend seeking advice from a primary care doctor for further evaluation. Hope this helps. Dr. Sheppe
