hi!
I'm not sure about your history, (on phone so no sig...) but you only just had a baby didn't you? it is normal to be tender etc... and it does take awhile to recover. firstly take something so your not constipated. last thing you want to do it push. alsoaybe drink some cranberry juice to help your urine, will help prevent infection and can stop it burning.
is it sharp pain or ache?
