I just posted this question ...I am beginning to suffer from serious brain fog, extreme fatigue, on top of increasing joint & muscle pain. I do not have a support system to fall back on if I am unable to work and lack sufficient savings to stay afloat. I am a solo parent so I HAVE to work. I am at a loss and have nowhere to turn. :(

Yes... be honest.
At my worst I had to phone in just hours before I was to start work and say that I just couldn't male it... then crawled back into bed. And yes I felt horrible and guilty that I was letting my colleagues down... BUT... yes there is a BUT... but was very sick and on the days I did go in they would see me struggle and knew I was not well... especially when my speech was slurred and it was taking me twice as long to do my work... On good days I was great, on bad days I was absent.

I was a nurse assistance worked at my job for 10 years, I was in pains all the time ,the docter had to take me out because I had a blood clot in my lungs.been out of work for awhile. I do want to go back to work but the doctor doing think it's a good Idea. With God help I know one day I will.

Keep a log of missed days let your Rheumatologist know, I was told to stop working shortly after diagnos and I’m on disability; but I went from full time to part time against dr advice. I did a video on my disability process on YouTube
