I've had weakness in my legs for about 4 weeks. that's isn't going away. my doctor has checked my reflexes and strenght and said they were very good. i've had blood tests done and they are good too. what can this be.? i also had baby 2 months ago?

"Leg weakness" after a vaginal delivery is not uncommon, and the degree of "weakness" is affected by how much compression of some pelvic motor nerves may have caused this. Generally this perceived symptom will gradually improve over time.

It is not feasible to provide a meaningful opinion without taking additional history, physical examination and may be some tests. It would be prudent to see your doctor and discuss if you may be depressed. Counter-intuitive as it may seem, exercise may help. Start with low intensity exercise such as walking and gradually increase the intensity as tolerated. Drink more water. Wish you good health!
