[|Human|] it s not about giving blood. . . . It is about sitting in a chair at Macy s (a massage chair) and having it hurt my back. A large lump immediately (ten to twenty minutes after) appeared on my back. A lump almost as big as a golf ball. Three hours later it is the size of a quarter, as if it was a ball the size of a quarter. The nurse on call at the college (BYUH) told me it would go down, it was probably a hema...... and put ice on it. I did for two hours and no change, In fact it got a little bigger. If a blood vessel did break, how long does it last in lump form? If it is still there in the morning, should I go to the doctor? I do take extra strength excedrine (2) and ibuprophin (2) each day for some type of pain. Rebecca
[|AI|]  Hi, Dear,Thanks for your query to Chat Doctor. Studied your query in full depth of its details. Reviewed it in context of your health concerns. Based On the facts, You seem to suffer from-Aspirin induced bleeding tendency which gave rise to hematoma Lump on the back. The friction while massage for a long sitting might have caused the bruise, which bled due to the aspirin induced clotting defect, causing continued bleeding giving rise to quarter size lump on the back.USG / CT study if need be to assess the extent of damage to the bones and soft tissues of the back, would fix the cause of such a lump after prolonged sitting on massage chair. Long term use of the Extra strength excel Chat Doctor. You should hence go to ER-To check the Bleeding and clotting time defect if any as it would need special treatment from Surgeon / Physician Team. Hope this reply would satisfy you and would help you to plan further treatment with your doctor there. Welcome any further query in this regard, which would be replied in next session. Good Day!!
