Dear,
Half knowledge about body functioning is like having no knowledge at all,
It can create
stress and
anxiety now you are facing.
If you want to clear your doubt, consult a physician first.
No self conclusion.
It can do more harm than good.
You are not your doctor.
There are people who are qualified.
Consult them and get to a conclusion and worry if you have to.
And definitely you will not be having to.
Wish success.
