A couple days ago my scalp and skin started itching when returning from my trip to Oregon, back to my home in Nevada. I used a therapeutic shampoo this morning to try to relieve the symptoms whick only lasted a few hours. This evening I have a lot of pressure on the crown of my head. I’m currently undergoing menopause and have experienced a number of hot flashes daily. The only medication I’m taking is Xeralto for pulmonary hypertension and I’m on 1liter of Oxygen therapy in Nevada at our elevation. I didn’t need any extra O2 in Oregon. Plus, my blood pressure is currently high at 142/87 which is unusual for me. Any ideas on what can be causing this head pressure? I plan to call my physician tomorrow but any info tonight would br appreciated.
