Woke up with quite a painful ear-ache today and the loss of most of the hearing in one ear.
It's probably the result of mowing the lawn yesterday. I've done a quick check on "sinusitis" and "ear-ache" just to confirm my hunch. Yes, indeed, it seems allergic reactions are a common cause of ear-ache. Unfortunately swimming may also aggravate it as can wearing mp3 player headphones (while mowing the lawn). So that could spoil my coming summer holidays.
As I explained to someone I was talking to, I've got hay fever in my ear.
Some of my common sense responses seem to be supported - warm water to wash the ear, preferably salted so as to be antiseptic. I've found that doing a kind of deep swallowing also seems to help.
I'm still not sure about taking montelukast daily. After about three days it seems to destabilise me.
So today I'm trying a double dose of anti-histamines, remembering that the specialist told me originally I could take up to three one-a-days at a time. So far the relief is limited.
