Go see your doctor: Looks like you're already taking fluphenazine. Talk to your prescribing physician about your symptoms & concerns which may be a side effect of your medication (https://online.Epocrates.Com/noframe/showpage.Do?Method=analyze&monographid=29&multibrandalert=false; may require registration w/o fee).

Physiologic rxns.: Our physical and emotional health are interwoven. The body often expresses our emotional anguish through physiologic symptoms. This is further complicated by possible medication side effects or sometimes completely separate medical conditions. My hope for you is that you can have a comprehensive assessment that can tease some of these issues apart. Take care.
