Headache After Pull-ups

Hey guys i wanted to ask if some1 had this problem before. last 4 trainings, when i do my 1st set of pull ups ( i do 100 pull ups and 150 dips a day only training) i get severe headache in my right side of head, above ear and above eye) and few times it has did go away eventually, but few times it hurt for an hour or so. could this be because my blood pressure is slightly higher, or could it be something worse? anyway i hope some1 can help with this

go see a doctor. headache in the front of your head around your eyes is not the same as an exertion headache and could stand to be checked by a Dr.
