Thanks for writing to H.C.M.
I have gone through your query regarding loss of hearing from your right ear and most likely you have damaged your right ear drum by piercing by q-tip.
Though you are feeling as your right ear is blocked and it is similar to situation as observed in eustachian tube dysfunction
.But you have seen blood in q-tip is suggesting trauma to ear drum.
To treat this you should do-
(1) Take antibiotic orally.
(2) Keep ear clean & dry.
(3) Don't put any ear drop
to your ear.
This conservative treatment may treat you but if it fails than surgical intervention will become necessary.
