Ankle Pain Symptoms
From your answers (ankle pain for at least three weeks that is neither mild nor severe, with morning stiffness, but without fever, pain in other joints, or swelling), a number of conditions come to mind.
A sprain or tendonitis could cause ankle pain like yours.
Osteoarthritis could do this, especially if you are over the age of 50 or have had previous injuries to that ankle. Ankle pain in this condition is usually worse with walking.
Ankle arthritis may accompany conditions causing arthritis in other parts of the body (such as rheumatoid arthritis); past psoriasis, diarrhea or a sexually transmitted disease may be of particular importance to you (see arthritis associated with inflammatory bowel disease, psoriatic arthritis or Reiter's syndrome). While morning stiffness is typical of these types of arthritis, swelling is usually present.
There are other possibilities (if you can believe it!) and early treatment is important for many of these, so it is important that you see your doctor soon for evaluation.
If your ankle pain is already improving, you may just need to give it a bit more time; over-the-counter anti-inflammatory medicines (such as acetaminophen or ibuprofen) are reasonable to try unless you are already taking them or your doctor has told you to avoid these. If symptoms persist, see your doctor for evaluation.
