<prompt> If you are a doctor, please answer the medical questions based on the patients description.I had 2 teeth removed last Wed. and I have a large painfull lump on my jaw, not where the teeth were removed. It was a very difficult extraction and it took 2 and half hours before they were able to get the impacted wisdom tooth out. Could this lump be a blood clot? I also woke up this morning with the bruise from my neck extending down to my chest.  <response>: Yes, your concern is very true. As u said extraction took 2 half hr i.e. tissue handling is much more, this causes small vessels oozing postoperatively. This oozing produces collection i.e. blood clot hematoma as you correctly predicted. Also, tissue edema inflammation causes an appreciable lump. Need not worry. In my clinic, I prescribe choral forte, enzymes that reduce tissue edema. Even without any medication, it resolves, just that it takes a little more time. Hope this information is useful to you. Thanks. Regards.
