Just went through the Covid deal last week. I had significant lower back pain on Monday and Tuesday all day. Sore throat then started Tuesday night and then positive on Thursday. I should say, a lot of people just don't know what to do after recovering from Covid. I've recently read that patients with severe Covid can develop a systemic inflammatory response that can lead to lung injury and multisystem organ dysfunction. The anti-inflammatory effects of corticosteroids might prevent or mitigate these deleterious effects (I checked this info on the
CanadaDrugs site). But it is no doubt better to address a doctor.
