It's just the RSD! I have those "red dots" all over and I have had them since I first got RSD. I've had quite a few sores from them. To me they look like tiny blood blisters and the ones that feel slightly raised are the ones that turn into open sores. Thankfully they've all been very tiny so haven't had any really big sores. I'm sorry that you have such a huge one! *hugs* RSD just sucks all the way around.

The only thing I know to do is keep it clean, put antibiotic ointment on it and watch it. If it looks like it's getting bigger then get the doc asap. I've known many people over the past 5 years who have watched their sores get very big. One guy had them all over his legs and they wouldn't heal. It was horrible! I felt so bad for him. He started hbot and while it didn't do anything for his rsd, it did heal his sores! That was the coolest thing ever.

Hugs,

Karen
