Hello and welcome,
There are a few causes of this severe pain:
1.
preeclampsia and swelling or bleeding over the
liver. Causes severe pain more on right side but may be all over the abdomen later. Needs prompt treatment.
2. severe
gastritis and gastroesophageal reflux disease: Causes severe pain more on left and shoulder. Increases with food, there may be
vomiting too.
3. Gall stones: Common in
pregnancy and cause severe right sided pain more after food.
4. pain due to heart conditions. Severe, there may be short breath or increased awareness of heart beat associated with it.
I suggest that the best action now is to go to the ER and get an examination as the management depends upon the cause. After examination it will be able to have a more precise diagnosis and then proper treatment will be possible.
Hope this satisfies your query.
Thanks for using HCM.
Feel free to ask any more questions that you may have.
