Wow!! This is exactly what mine feel like. I was never really able to explain it in words but that's it. This is the only remainder from my flare in August so I am assuming it is permanent for me. My left foot feels this way from the ball up to toes and my right foot isn't as bad, mostly my toes now. Some days I feel it more than other days. It seems to be when my feet are cold it's worse but I really can't pin-point it exclusively to that. I do try to keep my socks on most of the time. When I wear shoes I don't feel the tingling as much but do have that heavy feeling. Some days I can curl my toes and some days they barely curl. Today, I can actually feel the tightness all the way up to my arch--don't have socks on so may go put them on to try and help. It's not painful to me so I am not on any meds.

I hope you can find some relief.

I always feel as if something is in my shoe under the ball of my foot or between my toes. I am constantly taking my shoes off and checking. I have switched shoes and sneakers, sometimes I wear slippers just because I can't stand the feeling!

I also have double jointed toes and lately I have noticed that the joints don't "pop" anymore. It used to be kind of cool to freak people out with them, now they are almost normal, and that's abnormal for me. Not sure if it is just age or what...

my left leg is my bad leg. i can't bend my toes nearly as much as i can on my right foot.

my feet are numb and i have neuropathic pain in them and my legs.
sounds like MS related sx's. maybe talking to your dr about a change of meds?
