Hello well its day 8 of taking sertraline, haven't felt bad bit jittery and headaches until tonight. Ive been having the odd sharp pain in the right breast and all of a sudden the most intense heat spread over my chest head & down my arms its happened about 3 times tonight only lasts seconds. Im praying its a panic attack but i don't have them, could sertraline do this. I'm so scare will end up in a&e at this rate thanks xx
