The other day, I noticed these reddish spots on my toes. They feel a bit sore, but not painful or itchy. One spot seems more purple than the other two. I often take walks, and I've suffered from blisters before, but it looks a little different. I read about chilblains and Covid toes the other day, so I want to make sure this is okay.

I dont think anyone on here would know if this is related to Covid. There is so much to learn with this virus. If you are suspicious then talk to your doctor, who will be able to advise you how to get you tested. If you develop any other symptoms then you must get a test.If you are in UK there are lots of testing centres available now.
