What causes numbness and swelling in the feet?
Patient: My foot fell asleep ..I didn’t not realize and when I stepped down my ankle rolled, I heard several crinkling crunching sounds.it bruised and swelled a bit. I can move it . I wrapped with ace bandage Took Advil,and iced. I can Wally on it but some pain Doctor: Hi,  You seem to have allowed continuous pressure on a prominent nerve at the back of the thigh, probably by sitting on a hard edge or sitting with the knee  bent for a long period of time.This has caused the foot to go asleep.   The crunching noises you heard most probably indicate ligament strain or tear.This can also mean a fracture of the ankle, if you have weak bones.Your first aid treatment is fine.However if its not improving in 3 days, then you will need an X-ray to check for a fracture.  Hope I have answered your query.  Let me know if I can assist you further.
