Constant gas pains and bloating?

I'm more on the C side than the D side, but I am able to go every day. Bristol 1-3 if i don't mind stool softener and fiber, but what is most painful is the constant gas and bloating. I get sharper pains in my flanks that come and go, which make me believe its gas. I have constant small bloating in lower abdomen that can flare and become more painful, sometimes its also more bloated like a ballon animal tied across my lower abdomen. I also get less painful but more general bloating that tends to move around. Generally stuff happens more on the left side though.
I've had a few happy evening where I've been able to pass enough gas for symptoms to longer be bothersome, but I can't seem to do it on command. gas-x doesn't really help. Yoga poses only help the odd time. its usually when I go to bed with pain and lay there eventually farting with my legs bent I can remember it worked. Its like I can't relax my body enough to let gas out. I have the usual suspects anxiety, stress and so on.

Please help! Its been ongoing for 9 months, with ups and downs but its never entirely gone away. All test are normal (still waiting for colonoscopy, but had normal upper endoscopy). I can also get "nervous stomach" when in pain, and then poop more frequently, but same consistency. I had two episodes before but this is the longest. First Dr i saw at my clinic was "its IBS" after checking my file and abdomen. My family doctor is of the same opinion. I've got health anxiety as a bonus 😀

Anyone have the same symptoms?
