Hi- Your situation sounds perplexing, but -- for all it's worth -- I believe you. What you describe reminds me of a lightheaded dizziness I have experienced due to allergies/sensitivities. I do not recall any buzzing. My suggestions for all they are worth are to consider allergies/sensitivities, any environmental factors that may have disappeared then reappeared (molds?), stress as a trigger. Also, by any chance do you have amalgam fillings? Some people have problems with these. I pray God will guide you and meet all your needs. I have been desperately sick, not knowing what hit me, but God knew and he healed me. I had severe allergies and God taught me my immune system was damaged by fear, that our bodies are made to be compatible with everything. I am a lot stronger since he gave me the grace to face my fears. God bless you!
