Lisa,
Sorry to hear you also are afflicted with this virus. My AB IGG numbers have gone up in the 700s and now in the 500s. I don’t feel much better in the lower numbers. I was first tested three years ago. I don’t go by my numbers. Some days I have energy then others and some days I just want to stay in bed. With the Covid-19 virus around, I don’t dare go out where others are. Not sure I could recover from another virus.
