Hi im dr.hema physiotherapist.
Yes its common to experience pain after c section until breast feeding or 2 years due to various reasons like
hormonal changes, ligament laxity,
calcium deficiency, protien or vitamin insufficiency or thyroid imbalance.
Symptomatic relief can be obtained by application of diclofinac
muscle relaxant gel, with hot water fomentation twice or thrice daily for 2 weeks.
You can include supplements of Calcium & Vitamin D in your diet which will help in strengthening of bones.
Physiotherapy exercise will also be helpful.
1]Start exercises to strengthen your abdominal and back muscles.
2]Maintain proper posture and body mechanics while lifting things,feeding with back support.
