I still have'nt wrapped any prezzies

I have about 40 or so

And to top it off my arms and legs starting to ache last night and this morning my back and neck are aching so much I can barely lift my arms up

I've been coughing and sneezing for days but just put it down to a cold, now my head is thudding and I fear the worst-FLU on Christmas eve and I have 4 kids

I've had it once before and I was in bed for a week. I'm off to the docs in a bit, in the meantime does anyone have any tips to get me through tomorrow?
