I recently had my LLETZ operation for removal of CIN3 12/06/15 and I was advised not to carry out any strenuous exercise for 4 weeks! I'm very much intoy exercise and run about 3.5 miles 4-5 days a week. I have been reading online and I'm still very confused about what to do! Does anyone know how long I have to wait beofe I can start running or any exercise? Is it 4 weeks or is it 1 week, please help?
