Oh, wow, my heart goes out to both of you.

I do know some of what it's like to deal with multiple conditions. It's very trying. I deal with sensorimotor axonal polyneuropathy (neuropathy affects both sensory and motor nerves), and Psoriasis and Psoriatic Arthritis (PsA), and a neuromuscular condition- "myotonia." (Also several other diagnoses; yet, these three are more than enough to mention.)

I usually end up moving to a different bedroom. I am often in pain, in severe spasm, jerking limbs -- esp. spastic feet/ankles in the night. If my feet get cool at all, they go into severe spasms. I am forever readjusting sheets, positions, pillows, getting more medication and/or putting on more topical lotion for added relief.
Our sleep schedules can be very different.

My DH (dear husband) is so helpful and compassionate. I am very lucky!
At the same time, he has a very demanding job and he needs his sleep.

I have somewhat of an idea of what it might be like for you and Alan.

Oh, darn, who needs a dental emergency on top of all else?

My best to you and to Alan!

Warmly,
DejaVu
