Hi welcome to Health care magic forum.
Thanks for choosing H.C.M.F.
You have got spasm on the right side of belly button. It is apparent as well. It is there for 3 days for every 4 minutes a part.
Most probably it appears to be due to gastric Hyper acidity. other causes are gallbladder
pain, worms pain, So i advise you to consult a gastro enterolagist for diagnosis and treatment. You may have to go for M.R.I. besides other routine tests for confirmation.
Wishing for a quick and complete recovery.
