I have asked the doctor if I need bloods taken to check my immune system but he says I’m fine and flu is just the luck of the draw… last flu had an infection too so had a dose of antibiotics to get rid of that – wish i was better – I miss running but i don’t have the energy to do too much and horse riding is taking all my energy away 2 – 3 times a week…. hopefully all the vitamins, omega 3 fish oils and echinacea is going me good and I’ll get over it soon!
