@tomberry Hi and welcome to Mayo Clinic Connect. Wow, first congratulations on beating the virus! How was your experience? Did you have a more mild case? Or did I misunderstand and you’re just vegging because of not being able to get out? Anyway, let’s get you back up and walking. We’re not medical professionals on Connect so we can’t make a diagnosis. But we can rely on our experiences to help.

Though I didn’t have covid, I did have a period of time where I was bedridden for 5 weeks. It’s amazing how quickly our muscles atrophy. Especially legs and our core muscles that support the stomach and back.
My legs were really weak too. Doing smaller walks daily helped as did walking up and down a couple stair steps each day, adding more daily when I felt strong enough. But just like you, my balance was unstable and felt like I leaned forward. My oncologist recommended a physical therapist. That was most beneficial. She pointed out that my core muscles had atrophied and needed to bring those back to life to regain stability.

Your symptoms sound very familiar so a suggestion is to try some easy exercises at home. There are several sites online for gentle core exercises for us seniors, and for restoring balance. Some are done in the chair without having to get on the floor. I do most of mine before getting out of bed in the morning with some simple pelvic exercises and leg lifts. One piece of advice I received from the PT was that seniors should never to do crunches. It can be detrimental to our spinal areas.

Definitely talk with your doctor if you don’t see any improvement with your walking. Have you done any strengthening exercises recently? Here a few web sites to get you started. But be very cautious just starting out not to do anything too strenuous or too quickly. Slow and steady wins the race. Wishing you good health! Lori
