Is this a good or bad idea? helppp?

i want to be a state trooper in about 7 years. But i have problems with my back. like right now its killing me and it hurts to just move. i think i just pulled a muscle. and i have put stuff on it but it doesn't work. my back hurts constantly though. and my shoulder does too. it pops and stuff idk if it pops out but i cant have it a certain way bc it hurts. ive wanted to be a cop since i could walk. and i wanted to go to physical therapy but my mom is afraid they(cops) will look into that and see that i went for my back. idk what to do but i know physical therapy will help i just don't want to ruin my career
