I have a hard lump above my navel and to the left of it. When i press down on it i feel nauseous n it is uncomfortable. I can also feel a strong pulse when i press down on it. I have been having other symptoms such as a late period, fatigue, head and back aches, loss of appetite, certain smells of food and other things make me queezy, tender breasts, and a sore stomach and some constipation. I do not know if these symptoms are related to the lump in my stomach so I am just curious as to what it might be and the symptoms.
