I sustained an injury playing football years ago when I copped the full weight of an opponent on the sternum.
I was able to carry on working (just) but it slowed me down a lot and took a full month for me to recover fully.
The worst pain I had while attempting to work though was one morning when I had just pulled up to do my first job of the day, I had a searing pain in my lower abdomen. I tried to walk it off but the pain got the better of me, so I went straight to the quack who confirmed my suspicion that my hernia now needed to be sorted.
Strangely, the next day and right up to the day of the op I was able to work, and after it was operated on I was back working within 3 weeks.
Dazmond, hope you are 100% again soon.
