I have a small pussy lump on finger first finger from thumb maybe 1/8 in size it is on side of first knuckle from tip of finger as it starts to grow I would slide a needle into it and drain the puss its a slimy puss it does not hurt but it does bother me when it full of puss and I hit it on something , I drain it and it starts to come back after a week or less . its clear in color it on a finger I have not injured , this has been going on for about 6 to 8 months , and I have drained it many times and it keeps coming back , do think it has something to do with the lubricant in my knuckle .
Hi, Dear , thanks for the query to Chat Doctor. I studied your query in-depth and I feel concerned about it. In my opinion-the slimy pus for 6-8 myths is due to the\" Amyloid Cyst\" or may be complication of the Digital Mucous Cysts (DMC)of the finger-just adjoining the nail skin cleavage. Treatment would be-a-Tb NSAIDs, b-Antibiotics to control secondary infection and the pus, c-Surgical Excision with debridement is definitive treatment, d-Aspiration with antibiotics cover -has 40% recurrence and could be tried in your case. For this ER-surgeon needs to be consulted by you for the treatment on the above lines. Hope This would solve your query. Wellcome again for any more query
