Very new to all this and just got results back of an ANA test (1:640). For the past few weeks I've been a tingling/numby feeling in my left leg, left arm and left side of my face (right side of body feels perfectly normal). I'm 25 and have had no prior health issues in my life. Initially I quite thoroughly was tested for stroke, clots, etc. I've had a ton of tests -- ecgs, CT scan on my head, chest xrays, more bloodwork than I can imagine and everything is coming back perfectly fine (other than the ANA test). The tingly-ness on the left side seems to get much more noticeable when I'm stressed (which I am currently very stressed given everything that's happened over the past few weeks/all the testing). I've also been getting chest pains for the past week which I'm wondering if it's due to the stress. Not sure if this tingly-ness is a first sign of what's to comethough given this ANA test result?
