Its 3 weeks since the last time I had this problem and its happened again today! Feel quite ill now, feverish, pain, stiffness and dizziness with a swollen, itchy and hot to touch birthmark with swelling that is spreading around the back of my leg to areas that have no birthmark on them.
I agree, physical activity seems to be a trigger at the moment however I was very physically active up until 3 years ago when I left the Army. It happened very seldom, maybe once, before my time as a soldier.
Anyway i'm a bit fed up now and not looking forward to a full weekends work.
On the upside I've got another appointment with a doctor in a couple of days. This appointment was made 3 weeks ago, the last time I was ill!!
