Can akathisia appear on its own without any medication causes?
I have been experiencing akathisia (or something similar) for months now. At first it was induced by caffeine (which I stopped consuming). But lately its just been happening randomly on its own without any medication causes. I am not and never have been on any meds that can cause this.
Its driving me crazy because everything about akathisia says its induced by medications. My doctor and therapist were stumped. Does anyone know what could be causing this?
Edit: If this helps; the severe restlessness started appearing a few months ago and was initially only triggered by caffeine. It started off mild and got gradually worse. And now, after having a single frappuccino or energy drink, I will experience days of fluctuating akathisia type symptoms.
They will typically be severe and last hours at a time, on and off throughout the day. Over the next few days it will fluctuate more rapidly for shorter durations, with “crashes” strewn out in between spikes. During these crashes I experience utter energy depletion and dissociation.
Then (sorry this is so complicated), I went on an anxiety medication thinking it would help. But it only made the akathisia (or whatever it is) more frequent and worse, and would occur without any caffeine triggers. While on the anxiety meds, I had a couple sips of a frappuccino (was supposed to be decaf, but I think they made it regular on accident). But 10-15 minutes later I started having the intense restlessness again and it was so severe and lasted days.
I am off the anxiety meds now (and have been for a few weeks). But I had a restlessness episode again.
Note: While on the anxiety meds, I experienced rapid mood shifts that mimicked bipolar manic and depressive episodes. And I have continued having said episodes after going off the anxiety meds. So me and my doctor are watching this, and considering the possibility that the akathisia type symptoms are due to the potential onset of bipolar disorder.
I am sorry, that is a lot of information. I am just really lost because none of my diagnosis have been confirmed yet. And my symptoms don’t seem to match any of the conditions I have researched. I am a psych student btw.
