Blood sucker

Today I went to the doctors to have a blood sample taken.
Recently I've been suffering really bad numbness in my right hand & arm, so much so that it's really painful at times & often wakes me at night.
Having gate crashed Ferguson's appointment the other week, the doctor thinks I might have a Thyroid problem.
If I do, that might explain a lot..

(Incidently needles & veins don't mix with me so well...I was a big scaredy cat)
