with in me these same symptoms you posted about were called many different things depending upon other accompanying symptoms most of which only a treatment provider knew of....

example did you know that just skipping a meal or not eating the right diet for ones body can cause a person to have every single one of the symptoms you posted. so can something as simple as not getting enough sleep, taking over the counter medications, prescription meds not the right ones or incorrect dosages /inconsistancy in when taking the meds....all of which I had the same symptoms as you posted and turned out to be the causes after much struggle with trying to diagnose these things...

other things in me this turned out to be depending upon other accompanying symptoms was....

bipolar disorder, PTSd, eating disorder, anxiety/panic disorder, psychosis, delusional, mood disorder, schizophrenia, depression, postpartum depression, Multiple Sclerosis, unintentional substance abuse (was in the room when others were smoking cigarettes, was in the room when others were smoking weed) chemical poisoning (when the painting crew were painting the next door neighbors home and the fumes were following the wind to my place and other air polutions) work stress, dissociative problems, breast cancer (yes men can get it too)....gosh I could go on and on about what these same symptoms were with in me over the years.....

the line in the sand only your husbands treatment providers can say for sure what this problem is with in your husband. the problem can be any or all or none of what any of us tell you it was with in ourselves, every day new diagnosis's/illnesses/treatments are being discovered. my suggestion is your husband keeps working with his treatment providers. they are the ones that know your husbands body, life history, body make up (genetics, chemicals, mes you name it) therefore they truly are the best ones to be consulting in situations like this.
