Sound like you need a second opinion. That's a common thread for a lot of us. Some of us have been through multiple Rheumy's before finding the right one. I've had like 6 now, the current one I have is okay, he is knowledgeable enough. He, however, has a tendency to do a bit of back stabbing to me, which both myself and my hubby don't care for. Unfortunately, I'm a military dependent and don't have a lot of options when getting Doctor's. It's usually the person that's assigned to you is what you get.
I suffer from sun sensitivity too, my skin burns and itches once the sun hits me. We only use LED lights now in our home. They are a bit expensive to purchase, but the last longer than regular light bulbs and use less wattage so your electric bill is lower too. It cost us around $130 for 12 LED lights.
As for your joint pain, I can't offer a lot for the pain, except that I use heat when I hurt really bad. I also use bengay, tiger balm, biofreeze, icy hot to rub on my joints when they hurt badly. I also get regular massages, I do stretching daily, and if I'm really bad I take shower as hot as I can stand them. If I had a hot tub around I'd be in it all the time.
Good luck at finding a new Doctor and I hope that they get you the help you need.
