Thanks for the query
The mole on your belly button and the pain under your diaphragm are two separate issues and not related to each other.
The pain under the diaphragm could be due to the IBS
. I recommend that you visit a gastroenterologist for USG abdomen to rule out acute causes of such severe pain
If I were to be your physician I would have recommended you to take Tab Buscopan
for the pain.
I also suggest the following
to be taken once daily before food for 7 days
2. Avoid spicy and oily foods
3. Avoid drinking and smoking
till you are better
4. Avoid caffeine, milk and milk products
5. Do not sleep immediately after dinner
I hope I was of help
