My health went to pot after a covid infection four years ago. Usual story - fit, active, healthy, mild infection etc and can now do less than people decades older. One of the things that happens is I get very nauseous and get sick if I change levels or move at a normal pace. Things like walking up a hill, getting out of bed too fast, head at a lower level to my body (looking through a bag, trying to get laundry out of the basket, picking something off the floor without my grabber). I’ve done another test today which shows my orthostatic tolerance has improved (great obviously), but I’ve been getting sick even more than usual the last six months and my tolerance for minor slopes, standing too long, normal movement (e.g. getting out of bed too fast as I need a wee), levels etc has declined, meaning I’m nauseous and actually sick more often. Anyone else like this and know why? Desperately keeping my fingers crossed!
