Ya know those charts they have in hospitals now which show numbers 1-10 with varying degrees of uncomfortable looking faces beside each one. I'd get me one of them; point to the 10 and tell them in no uncertain terms it needs a bit more than Alleve AND the pledge/promise of all hospitals, etc. THESE DAYS is one does NOT have to deal with such awful pain. It is detrimental to healing, not just physically, but mentally...the emotional cost is terrible.
I'd get me a new internest/second opinion/something and GIT 'er done!! Then, I'd probably get a lawyer on the nerve damage thing, later on, but the pain HAS to be dealt with now!
