Being on the other side of the paycheck, DO NOT QUIT like previously mentioned. Your injury may turn into a "Soft Tissue and Nerve Damage" case that could'nt be confirmed except by "Does it hurt when I do this ?".
Just keep going to the doctor for pain, and keep sending in the note from your doctor. And keep all those records, and go to therapy, and keep feeling pain.
My worker comp insurance company settled with an employee to the tune of $100k a few years ago on a claim that never could be subtantiated with diagnosis, only pain. Actually, he had a stiff neck and sore shoulder, and the nephew call 911 just in case of heart attack. Of course no heart attack, but hospital administration sent him to county which set him up with social services, which referred to an injury lawyer, which came after my workers comp insurer, who got scared and settled.
