Lots of people trying to detox the shot these days: https://spikedetox.blogspot.com/
The biggest problem with COVID isn't COVID, but that people believe it's not curable or survivable. It's both. There are medications and supplements to help, but you also need to change your lifestyle and people find it very difficult to give up junk food, exercise, and get sleep because it's a long journey.
I second trying Ivermectin, but also Vitamin C, D3, and zinc. If you're not already off sugar and wheat, stop it now. If you try the above for a while and don't feel better, maybe think about detoxing the shot.
I found good advice from many sources. In Bryan Rosner's book "Freedom from Lyme" he recommends never throwing away medicines. I have boat loads of Iervectine for a parasite protocol I paused 3 years ago. Enough to cure a small army. Save your unused meds. You never know.
