We can't tell: I'd ignore the sed rate. It's helpful only if it is very high and lacks specificity. You probably have three different health issues. For each of these, you need a history and physical exam. I appreciate your interest, but there's no magic answers here or anywhere else to give a diagnosis to a mixed group of probably-unrelated findings.
