Update
Yesterday - gradually worse as the day went on. had to meet Mts Tel in Croydon for some shopping, was not in the mood, but survived it. By the evening I has started to sniffle and my throat was feeling tight and dry, then my knnes and and ankles started to ache.
Today - still sniffling and throat is not good. Knees and ankles seem ok but I feel incredibly tired and sluggish.
Arm still hurts as much.
Off to the usual lunch with my dad shortly. Don't really feel like it, but today would have been my mum's birthday and I can't rearrange anything as he is off to see my niece for the weekend.
