I am at this very place in my life. I have had so many symptoms since 2015/16. Rash that the dermatologist said was a possible side effect of spray sunscreen since it happened when I spent time in the sun. Tummy issues, muscle aches in trunk, hands, feet and neck. Heart issues that were undetectable on EEG and ultrasound. I had one doctor suggest I get mental help as he thought I was having a mental crisis. Finally in 2022 I was diagnosed with MCTD. I have had progressive brain fog to the point I can no longer remember words or things I have done. I am a teacher and my students are catching my mispelling. Words come out that I do not intend to say. I was afraid I had Dementia. Turns out it is brain fog. I am seriously worried one day I will forget who I am. My Rhumetologist says no processed food, no coffee, no sweets. I completly changed my diet thinking that I would get rid of the brain fog. It is not helping. I am not myself and have no idea where else to turn. My Dr is no help with this. I have no idea where to turn next. Any ideas or suggestions will be helpful.
