Is this anxiety?

For years now i have always noticed that every time i am in public or in front of anyone i dont know i am always really shaky, I always am looking behind me and i can never stop rocking back and forth. Its almost like i am terrified of being around people! I start to sweat, i feel like everyone is talking about me or is saying something in their mind about me. I also have these sweating episodes, like my body just switches into a mode where i just start to feel really hot on the inside even when on the outside i am extremely cold. As of late i have been waking up in the middle of the night sweating for no reason and there is a terrifying tingling sensation going through my body and it gives me goosebumps and i have to get up wipe the sweat away and kinda calm myself down. I dont understand it, i have been doing some research on anxiety disorders and my symptoms and i feel like that anxiety is the problem. What do you guys think? I also have MS and Chronic Pain Syndrome and i dont know if pain plays a part in anxiety
