Suggest Treatment For Lower Back Pain After Tail Bone Injury
A vasovagal response.
Detailed Answer:
I read your question carefully and I understand your concern.
Judging from those symptoms of heat sensation, sweating, distorted sound in the ears I think it was a typical vasovagal response. It is a response characterized by heart slowing and dilatation of arterioles (small blood vessels in the periphery), with lowering of blood pressure.
It can originate through different mechanism involving the brain or the heart. In your case it originates in the brain, initiated in a structure called hypothalamus which in turn influences cardiovascularcenters in the medulla. It can be triggered by pain or by strong emotional distress, in your case I believe it was a case of both.
It is transitory and harmless, so no treatment is needed, no worry.
I hope to have been of help.
