I am 48 years female ,have 1 child, taking calcigard retard 20 mg twice a day since 3 weeks ago (28/3/2019) when I started nose bleeding and was discovered with high blood pressure. I keep on having this dull headaches (uncomfortable headaches) when I shake my head I do not feel pain but I can feel the discomfort and dull throbbing of my veins in my left temple when I place my fingers and my head feels heavy all the time. I also feel sleepy during the day. and have double vision. My pressure doesn't change much too. Its about 156/98 what can I do? Should I change meds.
