My weird symptoms

I’ve had IBS for likely 40 plus years. I have something strange going on right now. I have a strange feeling like there is something on my left side, under the ribs. Sometimes, I feel it quiver, sometimes gas gets trapped and sometimes I get the slightest little pains in the area. I always feel the sensation. Things been going on for two months. I have always had strange bowel habits but is it normal to go once in the morning, then two more times in the span of an hour? I’ve been to my doc, had blood work and an ultrasound and everything is ok. What’s going on? I should also mention that this came on after a very bad bout of health anxiety which I’m still dealing with.
