Could 11 ng/ml vitamin d be the reason i feel sick? bone aches, fatigue, depression tired. shoulder hurt all day today. had cbc and vitamin d was bad

Maybe: Vit d deficiency has been linked to your symptoms, but deficiency is known to have no obvious symptoms. Best way to find out is to take robust doses of vit d & get sufficient sun exposure. You're in a northern latitude, you need longer exposure to sun (uvb rays) & more exposed skin. If doing this doesn't relieve symptoms but levels normalize, something else is wrong. If can't normalize GI ? Problem.
