Conversation: The conversation between human and AI assistant.
[|Human|] woke up day before yesterday with a painful small lump on left palm. Even with mag glass cannot see a bite mark, (thought might be spider) soaking had no effect, it itches a bit on the surface, but pressure on it is painful. I am a yarn spinner, and thought perhaps I had gotten a small cactus fiber from some fiber I brought with me from Tx. but see nothing, it is bit bluish and can see the curvature of the lump on hand . I am in my 70 s .
[|AI|]  Hi It could be an insect bite. If the lump is still there, better to apply some ointment (steroids 0.1% beclomethasone) and watch for any regression or increase in its size. sometimes it can cause severe infection of the skin, rather below the upper layer of the skin called cellulitis which need good effective treatment, like intravenous antibiotics. Better to get it checked out by a doctor as soon as possible if it continues to bother you.
