First i wish you the best of luck with your recovery, my recommendation would be don't trust your company's Dr. that they send you to. Get your own Dr. also. Best bet would be to have a MRI done immediately upon request of your own Dr. Their Dr. more then likely is getting a "cut" or fee for sweeping problems under the rug. You may need a attorney as well to help you with the rest. Do not inform them about your Dr. at this time and especially about your Attorney or immediate termination will happen.
This happened to myself at work and they royally mest me over! I have chronic back pain for the rest of my life from that accident but they got off Scott-Free since I "Trusted" them.
Just dont want to see another hard working man get reemed by the system. Hope its something minor but taking precautions are not a bad thing.
