Hi Dear, Welcome to HCM. Understanding your concern. As per your query you have leg tremors and arm weakness. Well there can be many reasons for symptoms you mention in query like essential tremor is the most common type of movement disorder , parkinsonian tremor , dystonic tremor , cerebellar tremor , psychogenic tremor or orthostatic tremor. There are other reasons also like arthritis , compressed fracture , pinched nerve or lack of sufficient blood supply . I would suggest you to consult neurologist for proper examination . Doctor may order CT scan , MRi of brain and spine , nerve conduction test along with taking history . Doctor may prescribe muscle relaxant along with anticonvulsant or antiepileptic drug along with vitamin and mineral supplements . For now do light stretching exercises and do mind relaxing exercises like yoga and meditation . Doctor may also refer you to orthopedic surgeon for other reasons . Hope your concern has been resolved. Get Well Soon. Best Wishes, Dr. Harry Maheshwari
