I’ll just add what I experienced. I didn’t have surgery, but was trying to avoid it for a torn meniscus. I was having pain from it and ITBS too. During my PT, I was also working out on my own at the gym. I developed pain in various places in my body, including my back. I must have strained my whole body trying to compensate. Anyway, I got the dry needling in my back. It really helped and I had relief the next day. I would definitely get it again. Also, the physiotherapist was very skilled and experienced. I feel comfortable with her, but would be cautious approaching anyone new. Just do research on the person’s qualifications and experience.
