My fiancee's left foot and ankle are swollen he says it's been hurting for 3 days but wa just noticed the swelling he also says he has a little numbness and tingling every now and then I looked it up online and it said a few different things but I wanted like a second opinion on what it could be.. I've seen achilles tendon rupture, achilles trndinitiss.. and blood clot in leg but I wanted to ask someone to see what we should do about it..
