Hi Dear,
Welcome to HCM.
Understanding your concern. As per your query you have develop hard lump after the blood donation. Well you have hematoma formation due to simple collection of blood due to minor injury to the very fine blood vessels under the skin by the needle during the procedure of blood collection. Due to this blood gets collected and causes swelling over the site. There is also possibility of infection at site but less chances . The swelling and pain will disappear if it is caused due to hematoma formation. If the swelling does not disappear within few days, you can consult your primary health care provider for clinical assessment and thus management. You can take a pain killer such as paracetamol round the clock till you see a doctor. Do not massage or do any type of compression or application over it.
Hope your concern has been resolved.
Get Well Soon.
Best Wishes,
Dr. Harry Maheshwari
