HEY! I had the same tumor thing in my leg.... hurt like a sunofagun!! the doctors took bone from my hip to replace the missing bone piece from the leg (when the tumor was removed) and help speed recovery, did they give you that option instead of cadaver tissue?
couple the leg tumor with the cancer I had I have a total of 5 surgical scars on my body, weeeeeeeeeeee! welcome to the club! and I wish you a speedy recovery and be thankful that it wasnt cancer.
btw- the doctors eventually told me that my benign tumor was a result of an old bone fracture that didnt heal right....who knows what the hell that means. heh.
