How long does your pain last?

I was recently diagnosed with fibromyalgia. The first RA that I saw wouldn’t diagnose me, because I didn’t have pain by touching me. The second RA did all of the blood tests too and since they all came back negative for autoimmune diseases, he says that I have fibromyalgia. In May of 2019 I was diagnosed with hypothyroidism, in December of 2019 I was diagnosed with trigeminal neuralgia. It seems that everything went crazy within a few months after my thyroid diagnosis, but I am on the lowest dose of medicine for this because my numbers are not very high at all. I have a lot of excruciating pains that only last for a few seconds to a couple of minutes (thank goodness) and will be in just one small spot on my body, bone, muscle, or sometimes it feels like a vein is getting ready to blow up. Yes, my whole body aches after laying in bed, but that usually goes away once I get up and get moving. In fact, my body will do that if I sit for more than an hour or so. Standing for more than a couple of hours will make most of my body hurt, but I usually blame that on a bad back. My long-term pain is usually from my sciatica nerve acting up, or my ulnar neuropathy. However, I did have a stretch where my arm muscle in my other arm hurt constantly for over 6 months. I guess I’m just wondering if any of you get these short term pains that hurt like crazy? They are very sudden and I can’t see where they are associated with anything else such as food, stress, lack of sleep, etc.
