A lot of weightlifters develop thoracic outlet syndrome (TOS). Paresthesia of the ring and pinky fingers is a very common sx with TOS. If there is compression at the level of C-8 / T-1, that can be indicative of a lower trunk brachial plexus injury. Just a thought, but you might want to be tested for TOS if things do not resolve. Process usually includes a consult with a vascular surgeon for TOS to be dx'd properly. It is not an orthopedic problem, but a neurovascular entrapment disorder. Check out our TOS forum for more info - there is a ton of material on that site. Best of luck to you and I hope you feel better soon.
