I am not sure if I am reading into this, but I feel like it must be one of my medications or a combo or something..

I get this like tingling feeling in my jaw and down my neck, and it seems to radiate into my chest sorta. It's not unpleasant, almost like a cooling sensation (not like burning or painful). It was happening saturday night, and maybe has happened some since then but at the moment it's bugging me because I don't know what's causing it and if I should be worried or not.

I re-started sertraline on friday (so today is day 4 of the meds). I generally take it at lunchtime with food. The tingling started about 4 hours after I took it. I also take a beta blocker (metoprolol) and blood pressure med (losartan) and neither of those ever caused something like this, although I did just notice it more after I took my beta blocker around 5pm.

I am trying hard not to freak out and go to the ER. I really need to sleep tonight! I hope someone can clarify. I also have acid reflex, my mom said maybe it's that but I don't know. The weird irritation feeling on the sides of my neck seem to be connected to acid reflux, but the tingling is odd.
