At what point would you see the doctor about a Plateau in weight loss?

I was going to suggest updating your goals in MFP.

It's supposed to revise your calorie limit down when you lose a certain number of pounds, but mine never has.

I have to go into Goals and change my weight that way on the website to get my calorie limit to update after weight loss.

It could be that your limit needs to be revised down a bit.

Yeah I was losing weight at 2200 cals (high activity, and loved calorie dense food). I wouldn't see why the OP could not lose weight on 1700 properly logged calories

So that said, the hair loss made me think about not consuming enough fat. Using the 0.35 X body weight (lbs) in grams as a minimum, OP you should be consuming at least 95g of fat per day. And that's a minimum! Now fat tends to be something that's somewhat easy to reduce when you're dieting. A little less oil/butter, drain the grease when done cooking, salad dressing on the side, log the whole packet of a condiment but really only consume a few dabs etc. Great for weight loss, But if you're regularly consuming below your minimums, your hair, skin and hormones (that control all kinds of things) may start to suffer. Check it out with your logging and eating patterns and see if any of this rings true

As for weight loss, I don't know. You've lost 83 lbs so your body clearly knows how to lose weight. Some people do gain muscle in a deficit - it's just not very common and definitely not the first thing one should jump to if they're not losing weight. All that said, I'm not 100% sure what's causing your stall of 2+ months, assuming you've been logging the same way and losing 2 lbs per week. I hope you figure it out, but like a lot of people are saying, I would try to sort out the basic, obvious things first. Who knows, it is possible that your body is functioning perfectly fine and doing a great job for you day in day out
