help! Lump in my throat

I had my 3rd fill on Jan. 5th and I finally felt that I was getting a restriction of what I ate. But reading everyones posts it seems that most of you are eating a good variety of foods. I have been so concerned with getting protein in that after 2 or 3 ozs I start to get that overly full feeling so then I don't get any veggies or fruits in. ( and I am so craving fruits and veggies) I have been getting in protein with powder mixed with V-8 Fusion Lite . But a few days ago I bought some seafood salad (fake crab) from the deli and thought I'd try it. I had about 4ozs for dinner and it went down with no problem. Then yesterday I had the same amount for lunch and I got this lump in my throat after eating. It is still there after 24 hrs. I purposely drank water after a little food tonight to make myself throw-up thinking something is stuck, but it's still there. It doesn't hurt but it's very uncomfortable and I'm having a hard time getting anything down. Any ideas?? Thank for any input
