I have TOS and it primarily was arm pain, specifically in the tricep area. I had the rib resection which helped some but after that did have some tingling in the hand which is controlled by meds now. I have had multiple physical therapists and while my current provider (Spaulding Rehab in MA) is the best and has reduced my otherall pain levels, I often have painful reactions in the triceps to strengthening exercises and trigger point massage. Interestingly, the only other TOS patient I've met never had finger tingling either, his symptoms were focused in the shoulder.
