I sent him a email today. I've lost weight and trying to work with it. I take two Advil and Tylenol in the morning and night, during the day if needed.

Hello, following the 1st and 2nd TKR, they blamed metal allergy and a test confirmed I am allergic to the metals used in the Cement (and it seems there is only 1 bone cement), following the 3rd TKR I asked the Surgeon if they knew why the joint failed and he said he didn't know as there was no obvious reason for the failure. The joint has a mild stafh infection and as I'm sure you know it's impossible to cure an infection. The condition of my bones and my age make amputation the only option and I'm not ready for that. I have been on a maintenance level of 500mg 2x /day of Keflex. Pain at my new knee is minimal as I have Demylinating Polyneuropathy which makes both lower legs numb except to nerve pain which is very hard to control. But much of the time, my pain is very well controlled by Pregabalin and I take the max allowed which is 300mg 3X/day. If I miss a dose I have very high levels of pain. I also take a 5mg dose of oxy daily. BTW, I don't know if everyone is affected by neuropathy the same way, but if my mind is occupied with a project that requires a lot of concentration, my pain level is reduced. Hope this helps - Ask questions if you wish...
