I m a 54-year-old female presenting with symptoms of nerve tingling and cramping in my hands and feet, causing them to freeze in an awkward and painful position. The symptoms have intensified in the past month. A few days ago, I finished a series of facet injections in both my lumbar (L4-L5) and cervical spine after a motor vehicle accident. Family history of diabetes and high blood pressure. I currently do not have either. I am relatively healthy otherwise, but under a lot of stress and have not been exercising for the past 2 years since the accident. I ve been drinking more water, thinking the cramping might be dehydration but it hasn t helped. I do not take vitamins, but saw online that the symptoms might be from lack of B vitamins and potassium, so I purchased supplements today. What could be causing the cramping and tingling?
