Hi Muse - welcome!
Regarding triggers - there are so many things that trigger increased pain for me personally a few that stand out are: temperature fluctuations up/down of more than 10 degrees, tactile stimulation, even the slightest bit of cool air touching my legs, busy environments, emotions, vibration like from riding in a car, noise, being startled, taking a shower.. oh the list goes on. Unfortunately avoiding all these things will only make it worse..
Here is a doctor who I've seen recommended by others in your area:
