Bumps and tightening of the masseter muscle - do I need more time to heal or should I treat it with something else? (Photo)

Hi, I had Ultherapy 3 months ago. About two weeks post treatment, the swelling turned hard and now the area of my jaw and masseter muscle is hard and there are two bumps on the right side that were not there prior to the treatment. My doctor said it is not a hematoma and asked iI clench which I do not clench or grind my teeth. She offered Botox but I don’t necessarily want a slimmer jawline, I just want to bumps to go away. Do I need more time to heal from Ultherapy? And why the Bumps?
