hi there, can you help please,

just a couple of weeks ago i noticed a bony lump below my left rib cage that is becoming more and more uncomfetable everyday. it is about 2-3inc wide and goes along my bottom rib bone.

i went to see a doctor and he sent for me to have a chest x-ray and blood tests. will need to wait a week for the results.

i the meantime i am left puzzled and waiting.

any ideas what this might be?

many thanks!
