I never hear anyone mention this as a symptom. I have low grade chronic anxiety all day and night, not acute panic attacks. Its a very nasty feeling to live with and I'm wondering if anyone else deals w/ it. I have CFS and fibro but anxiety (adrenaline, nasty sensation in head and entire body) seems to be a bigger issue for me. I heard it can be related to cfs but im thinking maybe its an entirely seperate issue for me. I have MDI so i develop many symptoms while taking medications, herbs, etc.... ..or i would take something for this awful feeling. Any suggestions? Ive tried SSRIs and went HAYWIRE! I have Xanax but i get electrical sensations and jolts in my body while sleeping.
