Shoulders and flare ups

It’s quite common for someone with arthritis to go into a flare after surgery and I think I might be about to have one.  Only this time I don't think it's got anything to do with the operation but I think it could be because I need my medication.

I have a Tocilizumab infusion every 4 weeks and I went for my last dose on 15th December, which means I was due my next one last Thursday.  Unfortunately, I can't have my infusion until 2 weeks after the stitches have been taken out.

The medication lowers the white blood cells and white blood cells fight infection, therefore isn’t a good idea to lower the immune system whilst trying heal.  This would be fine but my body is now feeling that it needs the medication.  I can always tell when it's time.  I sleep more and just generally feel achy and fluey, 2 really common symptoms of Ra.  My infusion is booked for 3rd February so not too long to wait now.
