Hi Matia, from beautiful Wanaka, the superb South Island!

I have experienced that every time I do something outdoors in the past few months. I try to do a task (I love mowing the lawns) and afterwards am just about crippled.

Yesterday I decided to tidy up one section of our fernery as it had got out of hand with months of neglect. It was not strenuous at all and only took about 20 minutes, then for the rest of the evening I was shuffling along - such nonsense. Being Friday night we went out for a bite to eat at our local shopping centre and my husband had to hold my arm and walk slowly with me while I basically shuffled. Usually I walk briskly - so I have two extremes now.

What baffles me, as it obviously does you - is why does this happen? There has to be a cause associated with our PN surely?

Do you have a diagnosis as to the cause of your PN, Matia?

I too would love to hear anyones expert thoughts on this.
