Ever since I started antidepressants, I have gotten extreme discomfort with my body. I have episodic headaches, feel tingling and burning sensation throuout my body, and it gets worse when I start doing physical exercise. I like to play soccer but I cannot continue after sometime not because I'm tired but the burning and tingling sensation gets completely unbearable. I have racing heartbeat most of the time and developed minor tremor as well. My body jerks ( involuntary muscle jerks (esp. upper torso) like getting electricuted) often. I cannot concentrate on my study or professors' lectures. I don't have psychiatric issues: I'm not depressed, I don't have any harmful thoughts, no psychosis, nothing. What all I have is extreme physical difficulties. I have a past history of anxiety and was on meds as well but I didn't have any of these symptoms. After having some anxiety issue again, my doc put me on antiDs and my life has been a hell. Self-analysing myself while referring to Google, I thought I had some brain disorder like Multiple Sclerosis or Parkinson's Disease but now I suspect I have extreme neurological problems (like superagitated nerves or nerve damage) from antidepressants. My doctor has put me on 200 mg of sertraline. I am on my 4th week on this dose but I still don't see any improvement (remind you my mood and cognition are fine. Its just these damn physical discomforts).   Do you think its just antidepressant messing me up or there is something serious underlying disease? (I don't have any genetic disease and my parents are healthy and don't have them) Can neurological test find out any nerve disorder caused by antidepressants (I very much suspect it is the cause)? Should I do CT scan/MRI of brain? I don't know what I should do. Anybody had similar experience before/ now. I need advice! Help!!
