See another doc
I have extreme pain on my left side above my waist and I went to the doctar and all they said was I need to stretch! Im sure im over exatragating but my side really hurts to me just having to stretch?
2nd opinion.
This is not a joke.
Sometimes we get into restrictive positions
when we sleep. This could be a blockage of some sort.
Learn to reverse your center of gravity. Some Yoga can help
you a great deal to get things moving again. Yoga for life,
but only if you want to live longer.
