I'm a 15 year old girl, 16 in March, that has been having extreme back pain in my lower back, only when I lay down. It hurts so bad I can't breathe. I plan on seeing a doctor about this, just wanted to know if anyone has any ideas. Its been happening for a couple months, and has gotten more frequent. I havent done any heavy lifting or anything I can think of that would cause this. I have Chronic Lymphocytic Thyroiditis and have been taking medication for it, but I'm not sure if thats helpful. Thanks.View Thread
