Hi sorry for your dx and pain. Not in my foot but I often times get such a tight feeling in my calves where it is hard to propel.I am on meds though which you don't want to take but if you change your mind a muscle relaxer may help or even like ant anxiety med that relaxes the muscles. For me it is important to have the right amount of activity and this is a learning process. Where I do enough that I don't become so stiff but not too much where the pain is out of control. I agree with the magnesium. The other supplements I feel are helpful is calcium with d and vitamin c of course the multi. I have read and on here too about omega 3 bring inflammation down as well if that could be also contributing. I don't enjoy this but most people like epsom salt baths too. Sorry this is all over the place. Hope you feel better
