<s>[INST] I have a sharp pain that periodically radiates from the outside of my left ankle up a few inches of my leg, not to the knee or above though. It lasts several seconds and then is completely gone. There is no swelling, discoloration, bumps, etc. and no recent injury although I am active. [/INST] Hello, I read carefully your query and understand your concern. Two common causes of ankle pain and leg pain are rheumatoid arthritis or osteoarthritis. This diagnosis should be evaluated by specific examinations. Meanwhile, I suggest using anti-inflammatory medications such as Acetaminophen to relieve the pain. Gentle stretching exercises can be helpful. Hope my answer was helpful. If you have further queries feel free to contact me again. Kind regards!  Chat Doctor.  </s>
