Another here. Very interesting about the itchy scalp, boheminan. Mine has been itchy of late, so much so that I actually ran a nit comb through it over the bathroom sink the other day in case of head lice!
The way rhinitis bothers me most is the headaches. They are really debilitating.
I take good old chlorphenamine (between 3 and 6 a day) which I have on repeat prescription from my GP. There are usually two or three months over the winter when I don't need it. It still seems to be effective but not as effective as I found Terfenadine which, unfortunately, though with good reason I'm sure, was withdrawn quite some years ago.
