A Lot Of Questions

So I want to know why it always sound like there are bats chirping or whatever that sound it is they make in my ears and how do I make it stop? It is going to drive me crazy! Is it normal to feel an immense pressure in my head all the way down my spine? Is there any way to make it feel better? Why is it that all of these new symptoms just suddenly came on? Are they all going to just get worse? I am so scared I am going to lose my ability to speak completely because my speech is going down hill pretty fast. When my hips pop I lose feeling in my legs and they are pretty much paralyzed for a while...kinda scary. Sorry for all of the questions...just curious about a lot of things and I figure that you all know the answers to them.
