My right ankle is sore on the right side and if I move it or put pressure on it, it hurts. Its been swollen for six days now. What should I do?

See your Dr. considering it is 6 days, Dr. may want to do X-ray/ MRI to evaluate for Bone/soft tissue including ligamental injury, after a thorough examination and history. .
Ankle. Was there any trauma to ankle? If yes, and you have tried or are able to take ibuprofen and iced it and it is still tender, see an MD and get an X-ray. If there was no trauma, see an MD, it may be a medical condition like gout.
