Honestly I don't want to worry you, but you need to give her ivermectin, and consider some of the treatments recommended in the FLCCC group. For your mom's symptoms it would seem that ivermectin, vitamin C, D, melatonin, aspirin, and omega 3's are helpful, but they might want her to take fluvoxamine due to the taste issue. I suspect that means she has some brain inflammation. Most patients do because spike protein monocytes go to the brain. The following should be given to your mom regardless to mitigate longterm issues. I suffered for months due to not knowing of these protocols, and likely suffered permanent fibrosis as a result which I am now having to research how to reverse.
Take a look at the protocol below.
