So sorry to hear about your passing out. Are you sure it is from the pain. Others here suggest you should get it checked out - I agree.
I also passed out last Sat. I posted about it and got several responses. I really hurt my back and am still in severe mid back pain - dificult to bend over to do anything - brush teeth, also can't do any twisting, lifting. It just hurts to take a simple jar out of the frig.
I passes out in the kitchen twice abouty 10 AM. I did see 2 doctors. Both seemed concerned at first about the passing out but then dismissed it.
Thus I am not sure how far you would get when you see a DR. They really don't know what to do. Maybe MRI brain scan or something.
Could it be from the medication. I am wondering if mine was from the med. since many say "causes dizzines", Check your med bottles - maybe yours says that also. Check it out.
Best wishes to you - In His Hands/ You are always so kind to respond to others.
