(i.e. car crash) i had been rear ended 3 months ago. i had been stoped in traffic at the time. i injured tendons on my right hand which swelled, nothing broken. my left hand ended up with a ganglion, and 4 weeks later i got a lipoma on the mandibular area of my neck,so i find it hard to belive that trama is not linked to lipomas. i had been hit at 45mph. my head blew forward and bounced off the head rest of the car seat. i did not have pain in my neck area. but did have tenderness warm type activity .
