Last Monday Morning I Woke Up With Severe Lower-back Pain;

Last Monday morning I woke up with severe lower-back pain; I think that I caused that by carrying bags of soil on Saturday. But Wednesday evening I started to get body aches in my shoulders. I have very low energy and my muscles ache and are weak and my skin is sensitive to the touch. I eat every meal and am not nauseous. Can you give me an idea?
