Did I develop an allergy?

So for the past few nights I have been having stirfrys, and as a sauce I put in sun dried tomatoe salad dressing to give it extra flavor but lately, after I eat it about an hour later, I can't move because one slight move and I feel like I'm going to be sick! I don't eat much maybe about 2 cups of it and I'm full so it's not that I'm over eating! Same with spaghetti, I have tomatoe sauce on it and right after no matter how much I eat of it, I still can't move cause I feel like I'm going to throw up! This goes on for a good few hours of this not being able to move! Like I can get up to walk around but I feel really nauseous and I look really pale in the mirror! So did I develop an allergy to tomatoes? Or is this an intolerance? Thank you so much for answering!!! This has been going on for at least a year or 2! But I never really thought much about it till I started using the salad dressing! Then I put 2 and 2 together!
