It really does sound like discoid lupus, but the best if not only way to diagnose it is through a skin biopsy. It is probably time to ask for one of these to be done, possibly by a new dermatologist if you have lost faith in the one(s) you have seen before.
Discoid lupus can turn into or also present as systemic lupus, and given your other systemic symptoms of joint pain, fatigue, headache, and the positive ANA you may also want to ask for a referral to a rheumatologist. This doctor could order more blood tests or also send you for a skin biopsy with a dermatologist he/she knows well and knows about discoid lupus.
I think it's time to ask to see a rheumatologist (aka rheumy!) and hopefully you will really start getting some answers and some treatment that will help. Best wishes & I hope you'll keep us updated on how things go. And welcome!
