Last night I had tomatoes and suddenly I developed swelling on my hands and fingers. The swelling was more on the left hand and middle finger than right hand. Since morning the swelling has decreases abit but not completely gone. I feel abit swelling on the face under eyes. I had swelling before but it feels okay the next morning. But today I am having swelling. What could be reason of swelling? And if it is due to tomato allergy then how long does it stay?
