If you suffer from jointpain then this can spoil your whole day. Things that are otherwise enjoyable suddenly become painful and they form a challenge you are not looking forward to. The annoying thing is that normal painkillers like aspirines only help for a little while and will not keep you going the whole day, unless you really take a lot of them and that may have other bad effects. I'm glad I don't have that. Like today, without many problems I painted a table on the terrace and I didn't have any pain. It was a good day and I want more of those!
