Hi i just found a little lump on the right side of my stomach. Its pretty deep in the skin and about the size of a pea. Its located just under my lower rib area. Ive also been having some discomfort in my lower adominal area... it comes and goes but i mostly feel it at night when im not active or lieing down. At first i thought it might be an ulser because i do eat spicy foods but now i think it might be my apendix. Im 18 years old, I do workout but because of this problem i havent much and ive always been in good health. please help me!
