My muscles ache way too often, way too much - is this probably fibromyalgia? if so, good home remedies?

other therapies? not much money to deal with it - so i'm trying to treat this pain on the cheap. also, if i see a doc, would it be a rheumo? i go to a chiro often, it helps, but only for a week or two at most. exercise almost always worsens the symptoms. hot water baths help substantially. stretching somewhat. i've tried MSM. other ideas?
