Hello! Welcome and thank you for asking on HCM! I understand your concern and would explain that a careful physical diagnosis of different disorders that may lead to this clinical scenario is necessary to be done: - an autoimmune disorder like rheumatoid arthritis, lupus, etc - a back bone disorder, like possible degenerations, slipped intervertebral disk, etc. - a chronic inflammatory disorder - Fibromyalgia - psychological disorder, like possible somatoform disorder. I recommend consulting with your GP for a careful physical examination and some tests : -resting ECG -chest X ray study -urine analysis -cervico-thoracic-lumbar column chest X ray study -electromyography and electroneurography to examine the nerves and muscles -blood lab tests (complete blood count, PCR, sedimentation rate, blood electrolytes including calcium and phosphorus, kidney and liver function tests) Further immunological tests (rheumatoid factor, ANA, ANCA, ENA, etc.) should be done if suspicions are raised. Hope to have been helpful! Feel free to ask any other questions whenever you need! Greetings! Dr. Iliri
