This morning when I woke up, for unknown reasons, I keep feeling slight jerking or pinching sensations coming from my clavicle. In December I had a plate with 12 screws placed on my clavicle in order to heal my bone that was broken in 3 places due to a car accident. After further examining it I noticed that there is a bump sticking up where there was not a bump before and I am afraid it might be a screw. Is this possible? I don't know what to do! Help please!
