Have had clear, water like fluid draining from my ear in the last few days, especially at night. Cleaned with hydrogen peroxide and stopped due to excessive drying and some scabbing. Lot of colds recently in workplace though this is all I have noticed. Is there any home or over the counter remedy to try for a few days or a week to try and clear this up?
One caveat before I make an over-the-counter remedy recommendation: it would be best if your doctor determined if your eardrum is intact before you put anything into your ear canal. If you decide to see your doc, she or he may prescribe Cortisporin Otic suspension drops which is a combination of antibiotics and cortisone.
As far as "home" remedies: 2.75% boric acid solution or Burow's solution (aluminum acetate) can be used as an antimicrobial. There are no OTC steroid drops you can put in your ear, but you can use 0.5% hydrocortisone cream on the external part to minimize inflammation.
I would suggest you avoid shower or any other type of water (if you swim) getting into your ear while the healing process continues. You can use cotton balls to protect your ears.
Hydrogen peroxide is a good remedy to use occasionally to soften the earwax but it needs to be diluted because it can can cause irritation such as in your case.
If the heavier discharge comes back or this does not resolve soon, you should definitely see your doctor.
