Due to cutbacks at work am having to work much harder to keep up. Before Christmas had to see GP due to dizziness and he diagnosed vertigo and gave me exercises to help it. Over the Christmas period I have had a terrible cough and cold, shingles (ongoing problem with breakouts for many years), nausea, stomach bug, dizziness, extreme tiredness and insomnia and generally feel utter crap. Still have runs and nausea after a week. Prior to all this was a gym regular and love exercise, however I have struggled lately with putting one foot in front of the other. Have had hardly any alcohol or rich food, usually also have a good appetite and eat healthily. Am now due to go back to work and was hoping that the Christmas break would have left me feeling refreshed and better, I just feel physically very low. To make things worse, in two weeks I am booked for major surgery which will mean I will be housebound for at least 6 weeks. Can anyone please give me any magical advice that will help me get back to health as soon as possible?
