<s>[INST] Hi, I just had spinal surgery due to C3 and C4 slipped into my spinal cord. That was 3 months ago. I lost a lot of muscle mass. As I have been slowly increasing my walking I have started to get severe cramps in arms and legs. I am also constantly exhausted. What kind of Doctor should I see to investigate these issues. [/INST] Hi, Severe cramps in muscle can be due to calcium or vitamin deficiencies. You should consult a Neurologist or physician. Calcium and vitamin supplements can be taken for relief. Hope I have answered your query. Let me know if I can assist you further. Regards, Dr. Neeraj Kumar </s>
