My husband had lots of pain too. They wanted him to use the peg right away and they put water in it while he was in recovery and then started him on feeds soon after. At that time he could still eat by mouth but they wanted to ensure that everything was working ok. The actualy peg tube was ok and we had the same problem with eating too much regular food and doing feeds too close together. He wanted to gain weight so badly he would insist on both a regular meal and his tube feed trying to calorie load. I don't recommend it!
Tony had bad pain for about a week. Kept me up most nights and he did have lots of pain killers and he never asked for meds at that time at all. It did get better Thank goodness
I was proactive with the pain meds as I could tell he wasn't doing well and I called his family dr to put in an order for pain meds to be ready for me to pick up once he got home. They weren't going to send him home with anything either..
It will get better...
