Yes, the laser treatments directly on the joints where the crystals are present seems to work very well if there are crystals left that the Allopurinol does not break up (the formation of uric acid crystals in the joints is completely dependent on the saturation of the synovial fluid that fills the joint by the uric acid, and Allopurinol is excellent at lowering that saturation). I would think that yes, the laser treatment directly on the crystals and/or the joint itself is raising the temperature of the synovial fluid of the joint, but if the crystals are that bad, at that point there isn't much fluid left to heat up. It's all about lowering the saturation of the synovial fluid by the crystals.
I think her temps are high enough, 105 on the basking spot is hot enough, bumping it up to 110 is not going to make a difference on the crystals in her joints, especially now that she is taking the Allopurinol, after a week or two of taking the Allopurinol you will start to see serious improvement, and I would be afraid of needlessly raising her temps up to that range because you certainly don't want to stress her out any more than she already is...85 at night is very hot, and again, I don't think it's necessary at all. If she was suffering from something like an upper respiratory infection or some type of infection then yes, keeping her nighttime temp up high is beneficial. But she has gout, and is already in pain and really uncomfortable and exhausted, so having her nighttime temp up to 85 is only going to make her even more uncomfortable and disrupt her sleep...
Are you using a nighttime heat source, like a CHE or a heat mat? I would try a night without her temps being so high, see if you can get her nighttime temps down in at least the 70-75 range, I think you'll find that she will sleep much, much more soundly, be much more rested the next day, and have more energy. Keeping her nighttime temps up to 85 isn't helping dissipate the UA crystals in her joints, the Allopurinol is. I think restful, comfortable sleep in cool temps is going to be very beneficial to her along with the Allopurinol and the Serrapeptase from the Silkworms...by the way, is she eating the Silkworms? I'd try to give her a couple an hour or two before lights out for bed, the hit of Serrapeptase a couple of hours before bedtime may really help her sleep more comfortably and peacefully too...
