I am 42 slim walk an hour each way to work absolutely no problem. About 5 days ago I walked up the stairs at home to go to the toilet and I was completely out of breath and had to stop at the top. I then found the same every time I go upstairs.
I walked the same journey to work the last few days and it’s painful and I physically can’t manage any slight hills. I walked to get the children from school which is a light hill and felt like I was going to collapse with exhaustion.
Ive also been getting headaches. Any one else experience this?
