What causes sudden onset of headache with leg numbness?
Patient: I know someone is has just recently started getting a bad headache with a quick onset and when he gets them, his legs go numb and just give out. He has fallen once or twice because of this. He has seen his IM doctor and now is going for an MRI - they are looking at his pituitary gland. Can a sudden onset of a headache cause his leg numbness and weakness? His headaches do not last more that 10 - 15 minutes. Doctor: Hi,  First of all, a headache is a symptom and the causes of the headache can cause leg numbness. For example atherosclerosis, smoking, drinking, endocrine disorders and kidney diseases can cause headache and leg numbness.  Second, he should measure his blood pressure and if it were high, he should receive a medical treatment and stop eating too much fat and salt.  Third, the women who take oral contraceptive pills or a hormonal replacement therapy can suffer from vascular problems, so they should ask a gynecologist to adjust the dose.  Finally, the deficiency of vitamin B complex due to unhealthy lifestyle can cause headache and numbness.  Hope I have answered your query. Let me know if I can assist you further.
