I had my surgery on 3/24 and I don't have much problem with stomach pain...unless ur talking about the soreness from the incisions and yes, I still have that and it is awful. I am miserable trying to get up and down out a chair, in and out of bed, or when I cough. I will be so glad when that part is over! As far as the pain after drinking fluids, I definitely have that which is frustrating and makes it difficult to get in all of my liquids. It may sound strange, but today I actually figured out a way to drink without as much pain. I have to lean my head back and drink when I take my meds and realized that if I lean my head back in the same way when sipping on fluids, it really seems to help. It probably looks kinda strange but it's better than that pain!
