Hi, Hand cramping can have several causes, including dehydration, muscle fatigue, and nerve damage. It can also be a symptom of certain medical conditions such as carpal tunnel syndrome, peripheral neuropathy, or Parkinson s disease. The cramping could be related to a nerve issue if it is accompanied by pain, tingling, or numbness. The pain radiating from the buttocks to the legs could be due to a condition called sciatica. Sciatica is caused by the compression or irritation of the sciatic nerve, which runs from the lower back down to the legs. This condition can cause pain, tingling, numbness, or weakness in the affected leg. The causes could be a herniated disc, spinal stenosis, or (DDD) degenerative disc disease. It is important to wait for the results of the nerve test and MRI to determine the cause of these symptoms. In the meantime, you can try some home remedies to alleviate the symptoms, such as stretching, applying heat or ice, or taking over-the-counter pain relievers. However, it is important to follow up with a doctor for proper diagnosis and treatment. Take care. Hope I have answered your question. Let me know if I can assist you further.
