I have taken atenolol for over 20 years but suddenly my COPD got worse. Apparently I should never have been put on them. I week after stopping my breathing had never been so good but the only thing is my blood pressure went up and my horrible headaches came back. Put on losartan which has brought my blood pressure down but has done nothing for my headaches. 6 weeks and thought any side effects would have worn off by now. Any advice would be very appreciated
