Problem with left side rib cage, anxiety?

Alright so i get panic attacks and have anxiety disorder so i could just be stressing like usual, but this feels too real. I started to notice that my lower left rib cage seems like its sticking out more than usual. I started to get pressure underneath the rib cage above the hip. Now i have this lower back pain in the same area and underneath left shoulder blade, which i started getting after doing alot of sweeping( im tall so bending over). Sometimes i also feel like my left testicle aches. Im confused because i have also bet having a lot of gas lately probably from the food im eating. I also get alot of headaches.
