I have to have regular blood tests and i have never experienced this before, it is now starting to ache a little and it is quite a hard lump too. Please if any one knows why this has happend can you put my mind at ease i m starting to worry as i said it has never happend before.
[|AI|]  Hi, dairy have gone through your question. I can understand your concern.  You have gone for blood donation.  There may be some technical error in inserting needle in your vein. It leads to extravasation of blood in surrounding tissue which leads to hematoma formation.  It will heal gradually within few days.  You can apply ice massage for rapid recovery.  It has no relation with your blood disorders.  No, any testing or treatment is required.  Just be relaxed. Hope I have answered your question, if you have doubt then I will be happy to answer. Thanks for using Chat Doctor. Wish you a very good health.
