Hello. I was shopping in a store, (Homegoods), when I looked up I saw that the carpet I had been looking at had detached and was falling down upon me. The heavy metal latch hit me square on the forhead, and I quickly fell to the floor. I put out my right arm to catch my fall. I remained there stunned, then called for help. My head was bleeding. I was taken to the ER to check for concussion. While my head injury healed, the arm which took the full impact of the fall has become much worse. It has been 10 months and I have daily constant pain from my shoulder to my fingers. I have had many tests, MRI, X-ray, EMG, but nothing conclusive can be found. I had a cortisone shot in my shoulder and it helped for about 6 hours but then got much worse for about 3 days. What can I do?
