I have a large painful lump on my upper abdomen. It feels tender when I push on it. When I am just sitting it does not hurt but if i lean over which puts pressure on it it hurts. It is not really hard but if i run my hand over my stomach you can feel a big lump that has never been there before. I feel like if I could just pop this large mass my abdomen and chest would feel better. I notice when I run i get a dull pain where the lump is and I have chest pain and I have to slow down and walk. I never walk I normally run 3-5 miles a day. What could this be??
It may be a case of epigastric hernia.................u should do an ultrasonography of upper abdomen and parietal wall to make a definite diagnosis.
