You may need to take probiotics (comes in a pill form) this helps with the microflora balance in your intestinal system. Its a natural dietary supplement. This might be what your already taking though.
I had a lot of bloating and gas and abdominal pain after taking six weeks of antibiotics for cold problems, went to a natural health store and they gave me a Dietary supplement called Digest-All by MRM and GI-DTX and Ultra Flora Plus DF Capsules by Metagenics. These supplements help me more than what the Dr. gave me.
Do you know why you have this? Some things you may want to try are an elimination diet to see if certain foods are bothering you, a gluten free diet (ask your doctor to test you for this before you change your diet), digestive enzymes (health store), ask for a SIBO (small intestinal bacterial overgrowth) test or try eliminating carbohydrates for a short period to see if you feel better) and be checked to ensure you don't have ovarian cysts. Good luck.
