It wouldn't be a bad idea to get a cbc done (complete blood count) to rule out hypothyroidism. Headaches, sore muscles, weight gain, hair loss, fatigue, lack of sex drive, and mood swings are all symptoms of this. As far as acne and vomiting, I have no idea.
Also, if you pcp is anything like mine, you'll have to call and leave dirty messages before they will finally call back with lab results. I would definatly try to find out for sure what they are!
Good luck with this! I went undiagnosed with an underactive thyroid for about two years, and I understand how frusterating and tiring feeling like crap is! I hope you figure it out!
