Is your surgeon located where you can go see him? You can google anything health-related and come up with worst case scenarios, so I'm hoping due to lack of any physical symptoms, nothing out of the ordinary is going on.
I went back and read your original post, and if this your first time around with Propecia and Rogaine, I wouldn't be surprised if that had something to do with that. I don't know what LLLT treatments are, but it seems you are exposing your hair to a lot of possible shed cycles, all in a compressed period of time while your scalp is trying to recover from the 'shock' of surgery.
Like I said, it only took a minor shed on Rogaine after taking it for 10 days for me ditch the stuff. I watched a video from Dr. Feller where he advises you try and get through those shed cycles because it's normal, but I couldn't handle it.
