I am going out of my mind with pain

I know I live in Canada and I know in the winter it gets cold. I know that. And for years it never bothered me. I figure skated,... I walked to school in all kinds of blizzardy weather. Thats just what we do when we live in Canada.But as I have gotten more unwell with my fibromyalgia, the cold has become my bitter enemy. And today it is -15* (Yes, thats minus) and I just saw the news and they have issued a severe cold warning as it is going to go down to minus 25* tonight. And my body sure does know it. I am in such pain it is overwhelming. I just want to take a baseball bat and beatr the shit out of this arm. It's in such agaony I just want to stop it from the relentless throbbing. Throb,... throb,... throb,... pain,... pain,... pain,... I have taken 2 Tylenol and 2 Advil and smoked my vape yet nothing is touching this PAIN. It really is unbearable.

I don't know what to do? I just can't take this anymore,... what do I do? 

What do I do to get relief from this pain????????
