You seem to be having slight infection of the intestines and also indigestion; it could be due to the recent fever
where the normal pattern of digestion will sometimes get low. You can take some antispasmodic and digestive tablet. If there is no vomiting
or fever, you need not worry, this will subside. If there is no relief contact your doctor. Puberty
has nothing to do with this gaseous distension. Take care.
