I just bought a blood pressure minitor - I will receive it tomorrow.

I was lifting my hands up in the air and bent my head backwards when we raised the flagpole - so probably my neck has been strained. But it is three days ago, and I only feel I am getting worse (headache, pressure, cognitive decline).

Is it possible, that I made a new injury, or do you think I just have to be patient?

PCS/whiplash is a weird thing!!!
