I had that rotten virus (flu? covid? other?) over a month ago. After a few days of being wiped out I was able to get back to work, but luckily it wasn't too long before the Christmas break. Took it very easy then. But I'm still wiped. Main things are tiredness but being quite puffed or unable for any exertion. I used to go the gym three times a week for a good workout, so this isn't normal for me. I can go for a walk, but uphill or up steps I'm totally puffed. I had to run for a bus the other day and it wasn't normal breathlessness after a sprint, it felt like my lungs were suctioning together trying to get the air back in. Tried the gym over Christmas and couldn't cope. I love the gym but have no desire to go back yet. Anyone else taking ages to get fully back to normal?
