I had c4-5 fusion 7 weeks ago. Three weeks ago I was told to wear an Orthofix bone growth stimulator. Have to wear it for 4 hours a day for a minimum of 6 months. Four days after I started I noticed I was feeling a little off. The pain at surgery site seemed more painful than normal. Several days later I noticed some dizziness and vertigo. I also wear hearing aids and wonder if the magnetic pulses are interfering and causing problems in my ear. This unit is very uncomfortable to wear and keeps hitting the back of my head when I take walks. Feel a like a harness for horse. Anyone out there having problems wearing this unit? Thanks in advance.
