Welcome on Chat Doctor! You should know that your symptoms could be related to chronic inflammation or a metabolic disorder including chronic anemia, thyroid dysfunction, etc.. For this reason, I would recommend consulting with your GP for some other tests: - complete blood count, PCR, ESR for inflammation- thyroid hormone levels for thyroid dysfunction- ANA, ANNA antibodies-Rheumatoid factor-complete blood count for anemia. Further tests may be needed. You should discuss with a rheumatologist on these issues. Hope to have been helpful! Kind regards,
