Many thanks for that – I’ve been popping my hayfever tablets for a week or so, and rubbing the site with antibiotic cream (another recommendation I found online), which does alleviate the symptoms more than a bit; I’m glad I’m on the right sort of track, and that there may be light at the end of the tunnel – I don’t think my reaction is as severe as some I’ve seen, so I’m going to rely on the power of positive thinking and hope that a few months will see me through ….
