I have a long list of LC symptoms since onset in Sep. 2020.
Of those, severe brain fog and dizziness remain in full force.
I have seen 'improvement' (none 100%) in many of my symptoms, through prescribed medication/physical/mental health therapies.
Though they all contribute, brain fog has been the primary debilitating symptom making work impossible. I have also had continual moderate to severe dizziness and balance issues. I do not use a walker. I have not yet fallen, though it was kind of iffy a few times in the shower. We have a shower chair to use when I'm feeling particularly unbalanced. If I'm walking in an open area I have room to weave. If in a more confined area there is usually a wall, chair, counter, railing... handy to grab, lean on to, slide down to the floor from, to keep my balance or me from falling. Trying to always be hyper focused on where my feet are going helps me avoid stumbling. I have had Hearing and Balance PT where I learned some tips and very low impact exercises and stretches to help be more mindful and intentional in my standing and walking, but saw no real improvement.
Before LC, I was in good health and regularly walking 3-7 miles a day. I have been unable, since, to walk long distances. Depending on the day, only a couple blocks to maybe a mile without Post Exertional Malaise (PEM) kicking in and wiping me out.
I have been fortunate to have a local Long COVID Recovery Clinic within 75 miles with a good team of medical staff to guide me through trial and error treatments to be my best possible self. I hope you will find the same at the Cleveland Clinic. More importantly, know you are not alone.
We have a lot of things in common. I walked quite a bit and was an avid night time Milky Way photographer. I especially liked to go to Utah out in the desert or other back areas and photograph. But COVID has halted that. No way could I walk around at night looking up and photographing the night skies. I have to use some sort of support for any kind of distance like 50 feet. I use a cane or walker generally. Oddly I had never fallen although I felt like I was going to many times.
Describe what you mean by "brain fog".
