[|AI|]  Hi, Good Morning, Thanks for your query to Chat Doctor online Clinic. I have read your query in details.-Dear In My opinion, the cause of the lump is-Boil on the elbow-and there is no relation to the plasma/blood donation done by you. Causes-Moslty a bruise /insect bite-leading to boil of the elbow skin is the cause. I would advise you to Consult a doctor who would treat it with-Tb NSAIDs, Antibiotics if need be and this painful elbow lump would regress and go in few days time.Don't worry.-Hope this would resolve your query. Wellcome for many more queries to Chat Doctor from your friends and you in time to come. Have a Good Day.
