My guess is that you're eating more challenging foods that your wrap is not yet ready to accept. Many pastas don't chew to a liquid. Just because you're 3 months along doesn't change the fact that you need to eat slowly and chew your food completely before swallowing. It takes a full 6 months for most of the healing and a year for the rest.
Often when people move along with their recovery they begin eating more and more challenging foods, and have a little relapse in what they view as their progress. Listen to your body. Your wrap, when it's irritated by food that is too rough or large to be easily swallowed, can become more swollen again.
If your wrap doesn't like what you're sending down, back off a little. Be sure to always chew your food until it is a liquid/creamy consistency before swallowing. Sip water or tea afterward. All of this will improve as your healing continues. Don't try to rush things or struggle against what "is". Relax and go with the flow. If your wrap says "no" then believe it and eat more carefully. It isn't forever...you will get back to eating normally again.
Hang in there!
