Feeling scared

So I've been having these head pressure moments, when the back of my neck, head and back gets tight, like a balloon being blown up. I get lightheaded, blurry vision and my anxiety sets in. I do have ulnar nerve problems and trape muscle strain but I'm not sure if that's what's leading to it. I can't get the proper care cause I just started my job and my insurance isn't active yet. Only Valium work or benadryl so I'm not sure if its sinus or the actual nerve.
