Hi and thanks for the query,
It is possible that with the q tip you may have injured either the ear canal
or the drum leading to bleeding.
Do not ever try to clean the inside of your ear.
Traumatic injuries of the canal or drum normally heal very well so you can probabaly wait before you go to the doctor.
Keep your ears dry and do not let water to get into your ears.
Do not probe your ears or try to clean them.
There is no need for any over the counter medicines. It will heal on its own.
Regards, Dr Kishori
