I had a NASAH on last new years eve. To cut a long story rather short, there was no cause found, no significant treatment required etc. I feel better with each month that passes but am now at 9 months and still feel unable to return to work which is starting to bother me. I struggle with fatigue, feeling off balance, headache and neck ache, irritability when tired. My job is 12 hour shifts and is really stressful and I'm so worried that I'm not ready but at the same time feel like I should be as it has been 9 months.... surely I should be fit to go back by now?
