This may have been the case with your "normal" bloodwork.
Your symptoms of fatigue, muscle pain
and weakness could be related to low thyroid function, adrenal fatigue
, hormonal imbalances and/or nutrient deficiencies. Especially because your symptoms are getting worse, you need to see a doctor who will run a thorough panel of lab tests, including several thyroid tests (not just a tsh), hormone
levels, vitamin levels, and adrenal tests, who will interpret the results correctly in light of your symptoms, and be able to prescribe effective treatment. A comprehensive approach is the most likely to help you feel like yourself again.
