I was diagnosed with CVST (Cerebral Venous Sinus Thrombosis) on November 8th 2009. After 5 nights in hospital I am now at home and feeling good. I am currently taking Warfarin & Nootropil, for 3 months at this stage. I would like to start exercising again but am concerned how much to do. I used to run for up to 45 minutes 3 to 4 times a week and have regular weight sessions in the gym. I am 46 years old, weigh 63 kgs and do not smoke. How should I restart my exercise programme safely?
