You should lay off shoulder exercises for a while. TOS can be dangerous. A friend and long-term weight lifter recently ended up in ICU with this condition. Severe blockage of a vein can cause severe swelling in an arm (or both arms if you are unfortunate to block both sides at the same time). This could cause blood clot to develop. The blood clot could potentially be fatal if it were to break off and cause a pulmonary embolism. Go see a doctor if you are having swelling or other signs of impaired blood circulation. There are two references below. These have been selected as most relevant to injuries that would be seen in athletes. TOS may be treated with drugs to dissolve a blood clot and in severe cases may involve removal of the first rib to relieve pressure on the vein.
