I had a c-section a month ago and i went to my obgyn he said it all good but it still hurts and it burns a little, can i workout or have sex ?

Post Csection limits: After a c-section, hold off on sex, vigorous exercise, and heavy lifting until 6 weeks after the baby was born. You can start light exercise, such as walking, as soon as you feel comfortable. After the 6 weeks and your doctor's approval, work up to vigorous exercise slowly. If it still hurts, wait longer. Some women are able to do it at 6 weeks, but some not until 12 weeks.

Varies: Dr dimino's advice is typical wisdom, but some recent studies have suggested that it is safe to resume physical activity much sooner than has been traditionally recommended. A study by minig et al showed that the pressures exerted on the incision doing typically activities like getting up from a seated position exceed what one would have doing moderate lifting or exercise.
