Look at eardrum
The best way to know is to have your doctor or an ENT specialist look in your ears.
Very often when eardrum ruptures it is painful and the ear
can bleed. If rupture
is due to infection, cream-yellow discharge may follow. You may or may not notice a change in your hearing. If you do have a hole in your eardrum, your doc/ ENT will give you care and follow-up instructions.
