gallbladder 2 hida scans...different results

i had a hida scan w/cck done a couple months ago and was told 1% ejection fraction. my symptoms include feeling bloated, lots of burping, and soreness like an inch or two down from my middle (around rib cage/sternum area). i can't say what triggers it more but i'm pretty much always feeling like this, more so in the morning. i've had this for about 4yrs. but haven't gone any further until now due to getting pregnant. with both pregnancies the symptoms seem to go away. have had endoscopy/colonoscopy recently. both came back normal. went to see another gi for second opinion, had hida ordered again. went somewhere else. ejection fraction 72% this time? both hidas and ultrasound showed normal gallbladder otherwise, no stones, sludge etc. am glad it's higher, but what is to explain the bloated and just not right feeling i'm having. i feel like i have a bit of acid reflux like i can feel it in my throat towrds the bottom by my neck, but gi said he doesn't see any sign of reflux. any opinions of the situation? i'm also have very itchy palms and in the crease of my arms by my elbows and behind my armpits. is there anything that could be related? i ws also told to getmy liver and kidney enzymes checked. i had a regular blood test cbc (all normal) and abdominal ultrasound (normal)...would like some answers especially since trying to get pregnant again.
