[|Human|] I have a lump on my lower left leg, above my ankle - it appears to be part of the ligament running along the outer part of my leg. I do have Crohn s disease, and have had a history of colitic arthritis in my left ankle and top of my foot, which has been sore recently. The lump is hard, slightly spongy when you press on it, doesn t hurt. I am experiencing chronic pain in my ankle and foot right now, I suspect it s related. Any thoughts?
[|AI|]  Hi! Good afternoon. I am Chat Doctor answering your query. The lump on your ankle might not be related to your Crohn's disease if you exert chronic pressure on that location of your ankle inadvertently. This could result in a benign cyst called a bursa, which might also be related to the joint cavity. However, this could also be a manifestation of the extraintestinal manifestation of the Crohn's disease. I would advise you to get it clinically assessed along with related investigations by your treating doctor, and this would depend on its further course of action, if need be. Till that, you could go for a mild anti-inflammatory Chat Doctor.
