How Should Knee Bone Infection Be Treated?

Ok bear with me a moment, Im miserable. I used to be in PM but then I moved to wisconsin recently, and my doctr here doesnt think I need PM. He lowered my dosage which I understand, but now Im miserable. I called his office nd they say theres nothing they can do. I have had a bone infection in my rt. knee and just a year ago they took out a hernia mesh that ended up being infected. Without going into to too much detail, I am starting to wonder if its worth it anymore. I cant do anything with my kids really and I tend to think they woul be better off without me. I cant just keep being in pain ALL the time. I asked my doc to help me get back to a normal life and with the lower dosage Im miserable.
