Over the past few months I've been very troubled by my right ankle. It started off about 2/3 months ago when i was trying to sleep and my ankle just felt incredibly uncomfortable (I have no idea how else to describe it). After this it started happening every night, it then developed into happening during the day as well. And now sometimes there is a painful stabbing/throbbing just above the ankle and the other side of it is slightly swollen. Its really disrupting my life, I cant sleep and nothing seems to help, does this sound like anything?
