Hi Dear,
Welcome to HCM.
Understanding your concern. As per your query you have numbness in left foot and arms. Well there can be many reasons for symptoms you mention in query like insect bites , abnormal levels of vitamin B12 or other vitamins, potassium, calcium, or sodium , seafood toxins , poor blood supply to the affected area , injured nerve ,
herniated disk in your spine , diabetes , multiple sclerosis or
hypothyroidism . I would suggest you to consult orthopedic surgeon for proper examination . Doctor may order certain test like x-ray or CT scan for disc or nerve compression problem , physical examination and nerve conduction test . Doctor may recommend
physical therapy , which is very helpful along with particular exercises . Doctor may also prescribe
multivitamin supplement for quick recovery . Doctor may also refer you to
endocrinologist for thyroid or diabetes problem . For now eat healthy , drink plenty of water and take proper rest .
Hope your concern has been resolved.
Get Well Soon.
Best Wishes,
Dr. Harry Maheshwari
