Long story short, had blood test in A&E last Monday, nurse quite forceful and couldn’t get enough blood out of right arm so after 5 mins of prodding with the needle he used the left arm instead. Right arm felt dead for about 24 hours and now has come out in a nasty bruise. Arm is pretty painful, can’t straighten it, can’t lift anything or bend it behind my head... AIBU to go to the GP to check it’s ok? Doesn’t seem to be getting any better.
