im 15 years old. for about two weeks, ive been having a weird pain in the lower right part of my stomach. it feels sort of like the side aches you get when you run for too long. the weird part is that it only hurts when i put pressure on my right leg. ive tried pressing hard on that area of my stomach and i dont feel it, but whenever i put even slight pressure on my right leg i get this sharp pain. its not a really bad pain, but it is very annoying. sometimes i have to limp when i walk because it hurts whenever i step with my right foot. as i said, this had been happening for two weeks so its getting really annoying and it kinda freaks me out because i dont know whats causing it. nothing like this has ever happened to me before. why is this happening? appreciate any info. thanks
