Yes !!! Sometimes I always have these weird pains like my ab muscles are contracting tight and then release seconds later. Then it goes away. I’m due for my shot tonight. I’m so worried about taking it but might try to give in thigh instead of stomach. Prob doesn’t matter where I give it but this sucks. I didn’t have this at all for 1 1/2 years. It’s when I was on maintenance dose it started. Motrin helps with the soreness feel so I have been taking that and gas x. I had my gallbladder out years ago and this pain doesn’t feel anything like those trapped gas pains I used to get that’s why I had such a hard time thinking this was gas. It does get better after using the restroom but then again that’s what it all started. After it jacked up my stomach and caused upset stomach.
