On the Firday, I felt like I was 'stoned' although I don't take weed. I was on a website which told me this was normal.

What's worrying me, however, is that my kidneys have been hurting on and off one at a time since this morning and since yesterday, my left arm feels like it's had an injection in it even though the only needles I've been anywhere near are from earrings... which I would not be so stupid as to stick in my arm.
The arm also feels dull, floppy and heavy. PLEASE help!
I don't know if the doctor's open over the bank holiday weekend... so I have to wait until Tuesday
