About a month ago I had an allergy attack for the first time. This resulted in just my left eye swelling up, kind of like pink eye. A month later the same thing happened while I was playing basketball. At this time I just went home and took some of my allergy medication. After the swelling went down, I has some soreness in my left eye, and I started to get a headache. Now, two days later I still have a headache, and the left side of my face seems to be tingling and feels a little numb. Is this something I should worry about? Is the tingling a result from the allergy or could it be something different?
