So for about 4 days now my back has been hurting. I thought/think that it's because I've had this week off if school so all I've down really is lay in my bed. So I thought that could be it. A lot of it has subsided, but now at the base of my back between my "back dimples" is puffy and swollen. It doesn't like extremely hurt, but it's unconfortable to bend over or squat and things like that. Sorry my explanation is so vague, I just don't know what it is and don't wanna go to the doctor unless it's serious.
