Thank you for asking at Ehealth forum!
I read your question and i understand your concern. These are common complaint after c section. Give It some time,take painkillers, rest, o physio exercises and wait and see. Muscle relaxants and massage will also help.
I hope it helps. Stay in touch with your healthcare provider for further guidance as our answers are just for education and counselling purposes and cannot be an alternative to actual visit to a doctor.
Take care
