I notice about a week or two ago that a knot on the left side of my big toe on my right foot has appeared. Could this be from my arthritis that I have in my feet ? Also with early stages of arthritis does something like this appear so soon? Still not sure what form of arthritis it is that I have as,of yet. But the way it's acting I'm guessing it's rheumatoid arthritis. Since my last post I've started feeling it in my knees , and shoulders. I'm still feeling the symptoms from it but not real bad right now. But the knot on the side of my right foot really concerns me . Is a bunion trying to form or could it be something else that going on with my foot?
