Hi, I am experiencing brain fog and extremely low energy levels. Yesterday I walked for 2 miles and I was exhausted. I pushed myself to exercise because my rheumatologist said it would help with low energy. He was wrong. My joints and muscles actually are worse than ever before. It’s so bad that even my heels hurt along with my fingers and toes. I’m almost at my breaking point because my doctor doesn’t take me seriously when I tell him how bad the pain is now.
