It is abnormal. Usually the eyelashes will not hurt. Your problems may be caused by the eyes infection. You may feel hurt at the eyes. You could use some paste with anti-inflammation to release the symptom. You could also use the warm compress to make your eyes feel comfortable. You should also drink more water to keep healthy for your body.
Well, it is weird for your eyelashes to hurt. And for your situation, I have to say that it can be because of eye infection, or some allergies. For example, some cosmetic products, such as mascara and eye make-up, can be the allergy to them, and then, it can make your eyelashes hurt. At this time, you are not supposed to have these cosmetic products. Of course, if your situation is serious, I will suggest you go and see the doctor as soon as possible.
