I just want to say thank you to everyone who contacted me as a new user to the forum. I have taken to heart all the excellent advice I have been given and to help myself to get home from Nicaragua to UK at the end of February. I sent my husband to see if he could get any Prednisone from the chemist and 'yes' I now have some without the need to see a doctor here.
I have also SKYPED a friend in England who had PMR for 8 months before diagnosis and he tells me even if I start on the Prednisone it shouldn't affect the markers in my blood so the doctor should still be able to do appropriate tests.
The important thing is if these tablets now work, it seems likely that I have PMR anyway, and I should be able to take the 4 flights, a bus and 2 days of travel far easier than before. My symptoms, of course, thus far are getting worse so I am so pleased I listened to everyone.
I will keep you posted and hope to have good news in a few days from now.
Once again - thank you.
