Hi madam.you seem to have lot of problems.
Your ear pain while opening mouth is because of Temporo mandibular joint disorder.
I suggest you to consult dentist
for this and get it solved.
You intense ear pain, dampness in ears, reduced hearing suggest that you have a ear infection
. So I would suggest you to consult ENT specialist
and get yours ears checked.
I f you have already consulted , then you can use z hearing aid
for your hearing.
