I've been trying the creams for the pressure sores and the one that works the best is the 1% hydrocortosone cream, but it doesn't work for very long. In fact, I noticed that it works for a shorter period each additional time I had to put it on. So I decided to google "treat pressure sore" and found a Merck Manual page that says it needs to be dry (non-caking body powder), it needs to stop having pressure, and I need a high protein diet so the cells can repair the sore.
Googling brought up only one brand of non-caking body powder so I ordered that, but it won't be here for about a week. I'll go ahead and buy more of the 1% cream when I go to the grocery tomorrow, but I'll also pick up the 2.5% from Kaiser on Tuesday just in case it works better (I have to do labs there anyway). I thought back about the times I've had the awful pain and there's much more pain and it increases more often when I'm sitting up straight. I have almost none when I'm sitting in the recliner or completely reclined/in bed. This means that I'm going to stay on the bed and read a bit every time I reapply the cream, and I'll try to take breaks in the recliner. That should take some of the pressure off. I can't do anything about the protein.
