In the hip replacement surgery recovery room (August 27, 2015), when I woke up,(groggy from the anesthesia) I was covered in sweat. My first night out of the hospital (in the "re-hab center), I woke up in TERROR at 3am, with severe PRESSURE in my head, dizziness, slight frontal headache, ringing in right ear [my nervous system was reacting to vibrations of the wall in my room from an oxygen concentrator up against the wall in the adjacent room=first symptoms of CENTRAL SENSITIZATION SYNDROME--hypersensitivity to most all sensory stimuli: sound, light, smell, temperature, motion/ vibration, touch/pain etc. As days progressed, I had neck pain/upper left jaw pain, difficulty concentrating. unable to focus on a task, (BRAINFOG) excessive sweating episodes, waking up in the middle of the night with "linked" severe pain in HEAD and "new hip", (not knowing what was triggering what). I had vision problems/blurred vision, had several falls, difficulty swallowing/choking, difficulty with abstract thinking (unable to continue with my garment design & implementation endeavors), unable to get restorative sleep, PTSD episodes---- most all this continues 9 years post-op!!
