Your symptoms could be related to a metabolic disorder or a connective tissue disorder considering the joint and muscle pain. For this reason, I would recommend consulting with your GP for a careful physical check up and some tests to investigate for the possible causes underlying your symptoms: - a complete blood count, PCR, sedimentation rate for inflammation- blood electrolytes- vitamin D and vitamin B12 plasma levels for possible deficiency-thyroid hormone levels for possible thyroid gland dysfunction- Rheumatoid factor levels- Anti-nuclear antibody levels- a nerve conduction study to exclude possible neuropathy. You should discuss with your doctor on the above tests. Hope you will find this answer helpful! Best wishes,
