What does a red bump on an injection site indicate?
Patient: Hi, I donated plasma for the 5th in little over 3 weeks. I get blood drawn from the same arm each time. The last couple of times I have only had an injection mark which healed. I never had a problem with bruising. The healing process was pretty quick.This time a small pea sized red bump/ knot has formed at the injection site about 2 days post of donating. It has been 4-5 days since donating and the little sucker is still there. The bump feels a little warm at times but I would have to say it is more of an itch to want to scratch around the area. I did have work the next day as a dishwasher which can involve mild lifting but knowing me I probably lifted too much. I’m not sure though. What are your thoughts? Doctor: Hello,This is thrombophlebitis after insertion of vein for the plasma donation.Guidelines for better outcome are:- Ice application 3 to 4 times a day- In our clinic, we recommend anti-inflammatory drugs along with antibiotics as per the clinical evaluation- Local application of ointment with hyaluronic acid will dissolve it fasterHope I have answered your query. Let me know if I can assist you further.Regards,Dr. Bhagyesh V. Patel
