Hi,
Most of the women post delivery face this low back pain especially after C- section..That's due to Lumbar puncture.
TENS, Hot fermentation and some strengthening exercises would help.
Next Steps
Please continue hot fermentation. You can contact me if you are in Bangalore or can give you online consultation.
Health Tips
Back care recommended. Don't get up suddenly from lying position, instead turn to side lying and then come to sitting and then to standing.
Avoid bending and over head activity.
