Can the Ultherapy treatment be done in 2 separate visits more than 2 days apart? Also are these side effects normal?

I had the full face and neck yesterday now I have a few issues . First off I felt a horrible shooting pain in the top of my head while my fore/brow was being treated. Today:headache and numbness on the top of my head I woke up with a ball under my chin feels hard swelling? After 1 hr next part another level of intensity . The machine would not work so I had to leave she saidI could come back in a few days when repaired .Can the procedure be done in 2 visits a few days apart?
