Hi welcome to Health care magic forum.
Thanks for choosing H.C.M.Forum.
you have got a pain abdomen, on right side of bellybutton. You are getting the pain on and off, with a gap in between.
It may be due to urinary tract infection
, stone in the urinary tract
, or some infection of the caecum, or ascending colon
I advise you to consult a surgeon for diagnosis and treatment.You may need to have M.R.I. besides other routine tests for confirmation.
Wishing for a quick and complete recovery.
