I think that the Lord saved you from an unpleasant test at best. What an answer to prayer to have the PA that you had. I will pray that the medication, compression wear, and monitoring your B/P will shed more light on what you need for relief. I've heard from others about their reactions to the test, and figured that since I'm on a beta blocker that would be prescribed, I decided not to ask to have the test done. My then 15 year old daughter was to have it done and it was cancelled for her because she was already on metoprolol.
Praying for you, too, for your headaches and the noises you hear. This I understand well, but I don't have an answer for myself. I only have the symptoms. Headaches are always a "pain," but sometimes they really need to be looked into. May the Lord uphold you and give you the joy and peace that only comes from Him. Yes, being confined for any reason is a trial that only He can relieve.
Blessings and hugs,
