I have suffered from lympho in my right arm for five years now. I don't think it's an extreme case. Occasionally I wear a glove if my hand swells. Yesterday I started to feel unwell-just mildly headache-y which is unusual for me. This progressed during the day and I started to feel 'delicate'. I had an hour after work at home before setting off for the first session of an evening class 8 miles away. I told my husband I was not feeling too clever, and he made me a quick tea before I left. I spent the two hour session feeling cold and kept my wooly scarf on! By the time I got home I felt really quite poorly, I changed into pjs, gown and layered covers on top. I felt really hot, but shivery at the same time, and a little light headed. I was burning up when I got into bed, and thought I would have a bad dose of flu when I woke in the morning. During the night I woke up various times, but realised I was gradually cooling down. In the morning, I felt much better in myself, but my arm was hurting. I inspected it and realised I had a rash covering half of it. This started alarm bells ringing about infection in my arm. I rang the docs and they asked me to come in. The doc seemed concerned and said she was borderline about sending me to hospital. Turns out if it went worse I was in danger of septicaemia! I have been sent home with high strength antibiotics and have to check the rash doesn't extend and my temperature doesn't increase. If it does I'm straight into hospital. This really is just to make you aware of what could happen. I have bought a thermometer now and think if I had checked my temperature/state of my arm earlier I might have acted sooner. Hopefully this will be ok, I will keep you updated.
