Dried bloody snot

This might sound gross but this is how it is for the past 1 and a half month.

Since i joined the gym/swimming when ever i pick my nose and i mean usually more then 4 times a day dried bloody snot comes out, i do not pick my nose with my fingers very often it is just that those snotty dried bloody things in my nose have started appearing i have no choice to give me nose more space.
It has no effect on my breathing however nor have i got a bloody nose. I had never got a bloody running nose in my whole life. Anyone can find problems
Should i check it out with my gp ??
