That's unfortunate. I had some complications after COVID as well (with blood tests showing decreased T cell counts and a CD4+/CD8+ T ratio that's well below the healthy range. I think one thing that took me by surprise is just how COVID seems to damage the immune system in some people, causing T cell exhaustion (chronic exposure to an antigen causing molecular changes in T cell expression so there's more inhibitory receptors and they're not as functional). If you've noticed some strange symptoms a few months after having COVID, like thrush, unexpected autoimmune issues, or just feel like infections hit you a lot harder nowadays, I highly recommend doing a lymphocyte subpanel blood test. You can order them online. Might help clarify some things. I'm currently using a protein called Thymic Protein-A to increase my CD4+ T cell counts and it's been somewhat successful in making me feel better (doubled my lymphocytes which were on the low end for a few years in about a week), though time will tell whether or not it's ultimately a successful treatment (especially since CD4+ T cell counts increase at a rate of about 10 cells per microliter in healthy human adults). Just my two cents. Obviously it's different for everyone. But I think every bit of information counts while we're still trying to figure this thing out.
