I have noticed that since I have been pregnant, a few hours after eating, I would get this deep dull, very painful pain
in my upper back
. It is a very intense pain
, and walking helps. Also, I noticed a hot shower hitting my back helped a lot. It went away then came back 2 years later with the next baby, and now, I noticed that sometimes it comes back if I don't get my three full meals, for ex. if I eat once a day, I will get gas pains. Antacids don't help right away at that moment.
