What's wrong? symptoms: 1) can't lay on my front without ache 2) lightheaded 3) sharp chest pain every no and then 4) lower back ache

Multiple Aches/Pains: Without further details, it is hard to say. Do you only get light headed when lying prone? Can you trace the onset of these sx to a certain abrupt start date? Clearly, one would want to rule out lung or cardiac or aortic causes of your pain first, and if the sx don't clear very soon, i would see you doctor musculoskeletal-skeletal causes, such as costochondritis may be considered.
