I study mbbs 1st year and we have to do hematology practical where we have to prick our own finger. But I feel very tense d, palpitation increase, I feel nauseated during pricking my own finger. Also if anyone try to prick my finger due to reflex action I pull my hand back. But I can prick others finger and can do all the experiments nicely. Sir please suggest what to do at the time of exam. I am very tensed. Also I am very skinny from my childhood and my weight is 40. Initially at the beginning of this year it was 35 but then very slowly 5 kg increased when I started eating banana. Pls suggest what to do.
