... to those who say you're lucky to have people around you that care - yes, you are, and I'm sure you appreciate that fact.
But sometimes, when you are in intense pain and just don't know what to do with yourself, you cannot focus on 'chatting' because you can't focus on anything other than trying to alleviate the pain. And it wears you out.
My partner is in this situation at the moment (sciatic pain from spinal stenosis)... sometimes he stands or sits with his teeth gritted and his face contorted - he just wants to be left alone to deal with it. After the intensity of the pain wears off, he falls asleep in the chair, completely and utterly exhausted.
I hope people understand - and if they do, they will not take offence if you tell them that you simply cannot talk. The body shuts down the mind when you're really suffering.
Shingles is absolutely awful Marmite32 and I hope you feel better soon. This too shall pass.
