Could you go to a chemist and get some Anusol Wipes or other topical chemist treatment? (maybe from one far away from where you live ) or you could try getting some latex gloves, filling the fingers with water and freezing them. When they are frozen you place them against the affected area to give some relief, it doesn't sound pleasant, but my Mum swore by doing this.

I hope you sort something out and get some relief Meg.
