Did wk 2 day 2 on Tuesday and loved it. Got the bug. Was on a treadmill so made my walks fast and running faster. Rather than cool down I whacked it uphill and did a five min speed walk. Then a five min cool down. Came away hot sweaty and buzzing. Great thinks me. Tuesday evening instep of left foot feels tight. Yesterday tighter so I went for a long walk to loosen it. Went to bed early with the plan of getting up early to go to the gym before work. Kit packed and ready, then...... 3am this morning woke up in agony. Left foot completely seized up with calf the same. So bad I couldn't even bear a sheet on it. To make things worse a gout attack, left foot big toe. Nearly crying it was 500g of paracetamol, an email to the boss and a day working from home. Still in agony now. Can't put any weight on my left leg. Feeling extremely frustrated as my plan is going to be in tattlers until I recover. Fat was painless Fit is killing me. What a joke. Any tips on lessening the pain most welcome.
