Pyloric Stenosis / Infant Reflux?

My son is 7 months old and was diagnosed with reflux at 1 month. Not being satisfied with the lack of effort the pediatrician had in helping my son be more comfortable, I switched doctors. He is currently on zantac and has been for about 3 months and he doesn’t seem to be much better off. When this all first started, the vomiting was forceful but not necessarily projectile. My problem is that with the meds the vomiting is controlled but he is still extremely gy and uncomfortable. I can burp him for 30 minutes with little burps, an hour, 2 hours later he is full of gas. I ran out of the zantac for a weekend and 2 days off he was throwing up after feedings. All that I’ve read about PS seems to be pretty severe. My son is a healthy weight, reaching all the milestones and for the most, is a happy baby but is uncomfortable about 75% of the time. Is there such thing as mild PS? I’ve never seen “wave like” movement but I have heard sloshing of the stomach contents…also has hard BM’s. Im just having a hard excepting the whole reflux thing because he is still so uncomfortable. Been to a GI also, said it was reflux and will grow out of it… Seems to be the only answer they can give!
