I started a low carb diet two months ago. I weighed 215lbs. at 6'3". I am a 26 year old male. I haven't been this skinny since I was 20. Now I weigh 165lbs. and have somewhat increased my carb intake in the past couple of weeks. I still stay away from sugar. I used to eat tons of candy and cokes, but now I stay away. I still keep losing weight. I get a little worried. I'm not looking for advise really unless you have something besides "you should see a doctor" but what are the bad signs I should look out for? What point should I rush to my doctor?
So far my health hasn't gotten any worse. I feel fine. My muscles haven't gotten any weaker or sore without exercise. I can't stand how boney I feel. I hate how my butt hurts from sitting, hitting my bones on edges, and how uncomfortable it is sleeping when my pelvic bones stick into the bed.
Although you said not to say it, I must. Get to your doctor. It could be diabetes, a thyroid disorder, or other things. If caught early it makes them much easier to deal with. It could be from the lo-carb too, but because you said you are worried I would hop into the doctor office.
If it's because of lack of medical insurance, I've been there. There must be a free clinic or a clinic that will charge on a sliding fee in your area.
Sorry I dont have another solution.

As Lori mentioned, see a doctor asap. Weight loss can be diet related... or it can be indicative of a serious medical problem. The only way that you can know for sure is to get it checked.
On the diet related side, the simple answer is: eat more. The reason that you feel so bony is that you've likely lost a lot of muscle tissue. While protein intake is important for muscle maintenance it is not the "be all end all" for maintaining muscle. Actually, significant muscle loss is very common for low carb dieters (many tend to have a very low energy intake due to appetite suppresion as the diet progresses). Anyway, in the meantime, try gradually increasing your intake of carbs (try to stick with unprocessed stuff... fruits, oatmeal, yams, etc) and/or healthy fats (salmon, nuts, etc).
And, you should see a doc about this just to be sure.
