chest pains after RAT

Has anyone else ever had breathing/chest pain after doing a home RAT?
It seems for at least the first few weeks after taking a test i struggle with my breathing and heart rate can spike randomly. I know because i wear a fit bit and monitor everything. The Fitbit recently asked if i have low/high blood pressure in my family. I don't.
I had to take the RAT because of family wedding.
not vaccinated.
