Currently diagnosed with Tourettes, Bipolar, Carpal Tunnel, Costochondritis. Frequently smell things that aren't there (foul), with extreme sensitivity that has to be slept off. Also smell things that are real but will be oddly sensitive to them on some days. My field of vision turns black when I stretch backwards or crack my back. Blackness fades back to normal from upper left to lower right in very bright almost-pixelated colors. Would lose my balance and fall, be dizzy, but would not lose consciousness. Recent pressure in the back of the head above the neck. Occurs with pulsing sensation and the appearance that lights are flickering on and off. (whether in light or dark.) Hearing also becomes difficult and drowned out. Lots of dizziness. Also, recent leg twitches, spasms, charlie horses, and outright jerking in the legs that even wakes me up when im sleeping. Very painful, and even my love of bananas couldn't cure it. Wondered if some of this was stress/potassium problems/ or a neurological issue related to tourettes. Have also been experiencing pain in multiple places on both sides of the body in perfect synchronization that last no more than a couple of minutes at one time. (like thumb and thumb, or toe and breast, finger and toe, different combinations in perfect synch.) Very painful, ***** back. Do you know whats causing my pain and odd array of symptoms? That is, if they're symptoms at all.
