For The Past 6 Weeks I Have Had Mid To

For the past 6 weeks I have had mid to lower abd pain going to each side. My stomach bloats up and get hard like i'm 9 mos prg. It doesn't matter what I eat, my stomach is upset. I have tried clear liquids, no milk products....no help. Drs have check gallballder....one said it's not working the other said that shouldn't be causing the extended stomach. I'm at my wits end.....what do you suggest?
