The 1 case I had like yours was caused by the lower back being out of place.
Do you know if it is open or closed?

Yoga to strengthen core & lower back
3. Slippery Elm herb
Conservative Treatment Includes
Taking liquid chlorophyll to sooth and heal bowels
Massage of the affected area
Hydration, Eat slowly, avoid alcohol, avoid coffee/green tea, avoid junk food nuts/seeds/popcorn, chocolate
Eat a low fiber diet for a short period of time
I hope some of these tips help. Healthy Regards, Kathy Shattler, MS, RD
