Inquiry about cupping therapy for bedsores (story)

I am receiving physical therapy due to a traffic accident.

I am receiving acupuncture and cupping therapy every day during outpatient visits.

Are there any side effects?

My back is turning red with bruises, and something is swelling upㅠㅠ

I'm going every day because I think it's good, but I also do weight training, so I feel a bit uncomfortable and I think I get tired often... Sigh...
