I have been struggling with extreme fatigue, muscle weakness and brain fog for the past few weeks. Muscle weakness in calves seems to be worsening. I have been checked in the past for several blood tests including thyroid, anemia and vitamin deficiencies none of which showed anything significant. I also was treated with antibiotics for Lymes Disease (definite bulls eye rash) a few years ago and have struggled on and off with these types of symptoms ever since. Could there be a connection?
