Many thanks to all who wrote to me...my friend Roger went into hospital yesterday and sent me text messages to say where he was...my phone wasn't working! I've just come back from visiting him and I'm so relieved. After 8 wks radio he looks better than I expected. His skin is only slightly red and he's being hydrated and fed by tube. It's good to know he now has pain relief on demand. Thanks again for such a helpful site xx
