Pain that makes you stop jogging and then leaves you barely able to move hours later is not something I would simply label as normal at 8 months after a tummy tuck with muscle repair. Some tightness, pulling, or muscle fatigue can happen as activity increases, but severe or recurrent pain in the repair area deserves an exam. Possible causes can include overuse or strain of the repaired abdominal wall, scar tightness, nerve irritation, inflammation around sutures, a small hernia, or a separation/weakness that needs to be ruled out. I would stop jogging and high-impact core activity for now and contact your operating surgeon for an evaluation. They may want to examine you while you cough or strain, check for a bulge, and consider imaging if the exam is unclear. If you develop a new bulge, worsening pain, vomiting, fever, redness, drainage, or pain that does not settle with rest, you should be seen urgently. Once serious causes are excluded, a gradual return guided by your surgeon or a physical therapist is usually safer than pushing through the pain.
