I still have swelling along my jaw after having 1 barbed PDO thread put in there. I’m 8 days post treatment. Is this normal?

Thank you for your question, it is not uncommon to have swelling for up to a month after thread placement. If you are exercising before 10 days this will also cause more swelling. 

8 days is too soon to worry. This area in particular was likely irritated by the thread insertion and caused more swelling than the others. Give it time and ice as needed. I often do a 2-3 week follow up with first time thread insertion patients to evaluate and reassure.
