It does sound like you are doing fine nan, and all are normal detox symptoms. Pain is always a concern that's why I mentioned the doctor and it is great you have that resource if you really think you need it. But as you said that's behind you which shows that the body has dealt with whatever it was as a normal process of the fast.
Sunshine is great for many things, especially while fasting. Your skin condition may just need time but I have found some skin conditions do respond favourably to sunlight. I usually have eruptions after fasting though, in the big elimination push on fruit as soon as I finish the fast.
I can totally relate to your talk about rest/sleep and crap fabulous too. :) The body is an amazing thing and the discomfort is worth putting up with knowing all the good the experience is doing us.
