@alliexa I had that & still get it occassionally. I actually thought i was having chest pain bcit was that sharp & piercing kinda feeling. & most happened at night when I would suddenly move from laying on my left side. I brought it up to my doc. & she said it's normal. it's actually ur breast engorgement. she told me chest pain would be longer last & more dual achy feeling rather than sharp jabs.

I was told to take tums bc it's gas built up

I had heart burn. drink some milk, see if it fixes it
