Hello all, I am one year post viral meningitis diagnosis this month. I am not at work as I have had central sensitization of my central nervous system which gave me an over reaction to pain. So, I went back to work after three months and was pretty fatigued, then got whiplash and had corti steroids for about four weeks to calm inflammation down. It worked but made the depression worse. However, the specialist set me a cardio exercise program to do. Started really slow, now been doing it for ten weeks and do now 6 days a week 55 minutes of cardio exercise at the gym. Go every day a week but one and am now starting interval training on bike and treadmill. Its going pretty well but as I increase the intensity I get some pretty extreme fatigue after. Makes me really vague and spaced out. Can get a bit anxious when this tired too. Does anyone get brain fatigue after exercising? I am building endurance to be able to get through full days of work when return. Just wondering how the rest of you are exercising. On my exercise days I need about ten hours of sleep and I wake up really bad tempered but it wears off. I suspect the depression is worse in the mornings and I have read this is a pattern of depression as well. But, the exercise is the key method for controlling the depression and its working. I have to keep doing it, in fact I really like it but the after fatigue has some crippling moments. Sometimes I get to the point where I cant function, brain not working, really heavy in the limbs and have to lie down. This happens about twice a week or more. Usually after the exercise I can become like this and sometimes recovery is two to three days. Does anyone else experience this type of thing?
