Terrible pain after acupuncture/cupping for whiplash

6 months ago I (23F) was rear ended at a red light as the passenger. I’ve had severe back/neck/shoulder pain for months and hear constant clicking and cracking. After months of going to the chiropractor and not seeing results I decided to try acupuncture instead. I had my first appointment yesterday and after discussing my history with the doctor she decided to do cupping as well. This was my first time with cupping (not acupuncture though, for diff reasons) so I had no idea what to expect. She put the needles in and it was more painful then I remember acupuncture being. When she did the cupping some spots felt good and some spots I was in agony. At the end of the appointment, getting up I couldn’t even turn my head, I was in a tremendous amount of pain I couldn’t even touch where the pain was bc it hurt so bad. It’s been a day and the pain has subsided a tiny bit but I still have bad pain where she said I was “tight” in my upper neck and feel the urge to crack more then ever. My whole upper back is also dark purple from the cupping. Is this normal? Should I keep going?
