What's up with my symptoms? i'm very cold but don't have the flu or a fever. body temp of 95.18f, bloodpressure 112/88, postprandial bg 95. thoughts?

Get warm: Your vitals are stable, as is your bg. Depending on what you ate, the post prandial bg may be even a little on the low side. I would try a different thermometer as that temp is very low and if persists you would be at risk for hypothermia. If it is indeed your true core body temp. Than get into a warm bath to bring your temperature up and get checked by a dr. Best wishes.
