After a day or two of taking the PPI, after doing some Yoga poses for
indigestion (that turned out to cause
heartburn), my heartburns started. Initially milder (pain level 3/10). I also took antacids which helped. But I've been taking the PPI for 7 days now and it seems like the heartburn is getting worse (today for a short while the pain was around 5 or 6/10) and the antacid is less effective. The indigestion symptoms also remain.
