Does long term effect of COVID-19 include difficulty in walking and standing up?

Post COVID complications, especially those with hospitalisations are not uncommon. This could range for extreme muscle weakness, tiredness to serious complications including widespread clotting, neurological complications. It appears your father has been covered for the latter by medications, for the former, he may not have been covered adequately. For giving opinion more, I will need to have access to the entire clinical reports including pre, post and during hospitalised admission. Please revert and letbus discuss.

Myalgia and muscle weakness are often manifestations in patients affected with moderate to severe forms of the disease, often the hospitalised patients. The causes include effect of cytokine storm (often hospitalised patients) and binding of SARSCOV2 (COVID19 virus), to ACE receptors in nerves, brain and related structures. These effects reduce with time and might recover fully or partially, after recovery from the current episode of infection and hospitalisation. There are various after- discharge, medical treatments and physiotherapy/ rehabilitation interventions available, which could give relief and could be undertaken under advise from the local, treating physician/ neurologist and rehabilitation physician and physiotherapists.

Again, as mentioned, the post infection episode symptoms and signs could mimic the acute phase, which means the fever, sweats, malaise, bodyache, respiratory distress could happen. These happen primarily due to residual damage by virus and also due to existing dead virus particles leading to immune based reactions.

Hyperhidrosis could be caused by instability of autonomic nervous system, as well, can be complication of COVID19. Your friend must be continue to be supplemented with Vitamin C (500mg twice daily), Zinc (50mg thrice daily), Vitamin D3 (1 capsule=60,000 IU ; 1 capsule once weekly), Capsule Saccharomyces Boulardi (1 capsule=250mg twice daily for 7 days). She might need some other medicines like N-acetylcysteine for a few days for preventing lung fibrosis, Thiocolchocoside (with/without paracetamol) for myalgia and pain, levocetrizine for congestion and upper respiratory tract symptoms and anricoagulant medications as per local physician's assessments. For Hyperhidrosis, certain medications such as anticholinergic medicines are used, prescribed by the treating physician, doctor.
