Pain relievers?

Pain is so darn weird! Here I am taking oxycodone for my broken leg, and it relieves that pain, but it won't relieve the pain from what I fear is a pressure sore on my heel inside my cast! How can that be? How can it be pain selective??? I imagine the oxycodone saying to the little pain signals as they go by, "Nope, not my job - I am only hired to deal with broken leg - you guys just go on up to the brain and have a party." And they do.

When my doctor put my cast on, she had her 16 year old daughter helping her and daughter didn't know not to press in at all. Doc saw her doing it and cautioned her not to, (daughter was holding my foot) but I think she did press on my heel before she knew not to.

Anyway, I have a couple of bumps on the inside of my cast in the heel area and it feels just like a blister formed by wearing new shoes that aren't broken in. I mentioned it to Doc during last Thursday's visit, but told her it seemed I could shift around and relieve it. Since Saturday however, it has been getting more and more painful, and no position really relieves it now. All this was complicated by the fact that Monday was a holiday and Doc is only in the office on Mondays and Thursdays. So, I go see her tomorrow and see if maybe she can cut a little window for my heel to heal. (Love the homonyms!) I'm sure if I had raised a fuss she would have come in earlier, but I don't think necrosis has set in (although it may be just the Xanax keeping me from catastrophizing and it really has set in - necrosis, that is. Or maybe the flesh-eating virus!!)

Anyway, that's my whine for the moment! Now off to search the web for vital information!
