I also had/have fasiculations, painful calves, and a bunched sock feeling under my toes.I was on magnesium and it is better, Now it is numbness in three toes and hot feet with tingling. I had covid about a year ago. I recovered ok. This all started in September, and keeps progressing. I am on a small amount of Lexapro. It helps with the depression of going from 100% healthy to 20% of what I used to do.... I look normal to everyone but I am in pain/uncomfortable all the time. I think my gabapentin is too low 100 2x day....
