I have been getting very frequent squeezing sensations in my left foot--alot of times it is along my arch, sometimes on the top by the toes. Is there a way to know if this is sensory, or if my muscle is spasming? I look at my foot when it is happening to see if there is clear movement, and I don't see anything specific. I do have frequent muscle twitching in this foot. Just curious if anyone has this, or has an idea of which one it's likely to be.
