After 3+ years dealing with this stuff I think I qualify to answer this. MY answer - Yes, Yes, Yes!!!I felt everything from cramping, twitching, mouth issues, speech seemed off, felt like I couldn't talk or chew correctly, back pain, finger and toe dancing(twitching), muscle pain, big twitches, many twitches all over, tingling, numbness, clumsy, cold affected hands, felt like I couldn't walk right, felt like I couldn't stand right, balance off, brain fog, swallowing difficulty, burning tongue, MAJOR mouth and eating issues( have resolved),tight forearms, calves, hands, shoulders, neck, fatigue, felt like I needed to sleep very day, every few hours. Muscle fatigue with minimal exercise or muscle use, cold spells, hot spells, dis-coordination, The list goes on and on.In case your wondering if I got checked out at all. Well, within the first 2 years I had 4 emg's, 3 MRI's, every blood test known to man( maybe not that much but I'm sure they took at least a gallon out). I had a full rheumatological work up, neurological work up, cardiac work up, immunological work up, metabolic work up, thyroid work up, Lyme, fungus, heavy metal, etc… I had maybe 4 different neuros, I also stuck with the best diagnostic neuro in our city for 1.5 years. I was monitored by neuro, rheumatologist, immunologist for a full year after I was told I was fine by all of my doctors. I'm also a paramedic so I have a pretty strong base of physiological and body process knowledge( this worked against me)I know your symptoms seem real and hell, they are definitely there but the reality is that after a full investigation by a doctor and especially a specialist resulting in a disinterested doctor means that whatever you have is a 99% guarantee to be from stress and anxiety. Stress and anxiety is a common thread with almost all of us on here and it's really probably the only thing that could cause such a wide variety of symptoms that would perplex the docs. Some will get *beep* that I said that but Just read through the forum posts and tell me you don't see it.Your wondering " could this really be from anxiety and stress" and your doctors are wondering " what in the heck else but anxiety and stress could cause all these issues".I hope that helps"Gods loves you and his plans for you are good" Have an awesome and hopeful day
