What Causes Swelling On Ankle?

Question : I've had issues with my right foot for a few weeks now. I went to the doctor with the outside of my right ankle and top of foot swollen. I couldn't stand to have the upper side outer foot touched with much pressure. They didn't find a fracture but my foot hasn't gotten much better. It's not as tender but still can't place pressure in the above mentioned area of foot. Have had spasms down my last two toes and ankle. My foot feels better when rested and swelling goes down. Then I'm back to working my two jobs and the pains and swelling come back. This morning, I moved my foot in the bath and felt a ' pop ' on the top of my foot. Like you feel when your back 'pops' or your neck. Site is still tender ( as mentioned ) Foot and ankle still swollen. I can bear some weight on my foot for a short period and can walk though sometimes it's painful on the outside of foot where issues started. My last toe has felt funny ( strange ) in the last few days... Bruising I had seems to be clearing up but when I'm active, I've been told it looks darker sometimes. Have had light spams in my ankle since the bathtub incident this morning. When this first began, I couldn't stand to have the bed sheets rub against the area. It's not quite that bad now... I had dropped a plastic bottle of juice on my foot from about 3 feet up prior to this but thought nothing of it at the time. Please help !!
