[|AI|]  Hi, Thanks for asking. Based on your query, my opinion is as follows.1. Possible injury has led to blood vessel damage.2. You are suffering from superficial thrombophlebitis, which is similar to after donation of blood for tests. Thrombus has formed inside, which feels like hard knot.3. Not to worry, it will dissolve on its own. The thrombus is too small, to cause any damage.4. Low molecular heparin cream application over the bruise could be helpful. No other treatment necessary. It will dissolve within a week. Hope it helps. Any further queries, happy to help again.
