Aches and Pains- does it affect your work?

I am having a lot of aches and pains, getting worse each day and I am still working as a homehelp for a charity for the elderly. Whilst I am trying very hard to keep going(I am having an MRI on Friday to see if anything is wrong) I am in pain most of the day now and don’t think I can continue much longer.
Has anyone had similiar problems where it has affected their jobs?

HiHazel ,I’m having the same problems as you.Some days I can hardly walk or bend ,my body aches from my neck down to my hips.I was having problems sleeping as the pain was wakening me up,my doctor has given me some sleeping pills and signed me off work ,but being in the house and trying to do some housework is hard going.take care meggy-moo x
