My brother, 68, is on blood pressure meds and statins and our paternal grandfather died from multiple strokes. That said, since late fall he s been having itchy skin in patches on his back, legs and arms - not all at the same time. In the past 3-4 days, he s been experiencing pressure in the back of his head that doesn t last long, but has been recurrent. He says it happens after he stands or changes positions. He has been bicycling approximately 150 miles a week in Florida since Jan 1st. He may still be very slightly overweight. The headaches are concerning for him and he calls me for advice, since I am a Medical Technologist. I ve told him to log his headache occurences and what he is doing when they occur. Do you have any thoughts as to what might be causing the headaches? I can t find anything specific in the symptom checker. Thanks.
