Hey this is really urgent. I'm female 20 years old. I can feel a stone like structure just below my left ribcage nd it pains if touched or pushed. I have no idea what is it, I noticed it in the morning n I'm too scared to tell it to my mom. Can you at least give me an idea what can it Be? I'm very scared of surgeries. Please tell me what is it. Just give me an idea what can it be.
