<bot>: Hi, thanks for sharing your health concerns with Chat Doctor!  In such cases of traumatic needle puncture or hematoma formation, generally I advise followings:1. Do not rub it2. Apply pressure for 30 mitutes3. Apply ice for comfort4. Use heparin gels for dissolution of the clot5. Take painkillers if the pain is not relieved6. If still not relieved within 2/3 days, antibiotics, aspiration and even physiotherapy required! Hope this answers your question. If you have additional questions or follow-up questions then please do not hesitate in writing to us. I will be happy to answer your questions. Wishing you good health.
