Thanks Loretta It looks like we are entering a whole new phase now. Reed started the clonidine patch yesterday, and his bp bottomed out soon afterward. It stayed very low today, and when I called the doctor's office to discuss this, the nurse told me she was going to speak to the doc and call me back at work. Instead, the doctor called me and told me to go home, remove the patch and check his bp every 15 minutes and check the color, since his foot had been turning black slowly and today it was much worse. So now, his blood pressure is back near normal, and the color is a little better but the doc is concerned that the injury may have caused a blood clot . He has to go in to see the doc tomorrow (he wanted to call a cardiologist and radiologist to get input before he sees him) and they are planning to do a vascular doppler at least, and preferably an angiogram. The pm doc warned us of the risk of spreading the RSD with an angiogram, but he said it was a risk that he feels has to be taken.In the meantime, we are checking bp every hour and he's not to be out of bed. If things turn worse over nite, he will be admitted immediately. I wonder if things are ever going to calm down.
