I am experiencing muscle weakness in my lower thoracic and upper lumbar vertebrae area, as well as in my arms. I can barely lift my arms past my shoulder level. Even mundane activities like typing and washing dishes are difficult, and I cant perform simple motor skills. This has been going on off and on for the last few weeks, but are particularly bad today. I am running a fever with a UTI, so I assume that it may be related to the acute symptoms of arthritis that I experience when I have a fever. I also should mention that I have Late Stage Lyme Disease that I have treated with antibiotics and herbal protocol. I am also experiencing some pretty intense cognitive issues, some mild confusion, mild narcoleptic episodes (my body jerks awake before it is really asleep) and pretty significant difficulty forming words from thoughts or printed word. I was just trying to read a bedtime story to my little son, and had to have my older child take over reading from me. I am beginning to be concerned that there is more going on here than just brain fog. Thanks for taking the time to help me figure this out. Kate Lindblom
