I am 66 years old and have been taking Benicar 20 mg. for HB pressure for almost 6 months now but I am beginning to notice side effects like legs pain during the night ,less urination, itchy skin,buzzing in the ear/head, poor sleep, skip heartbeat ..just a general sickly feeling ; this morning I decide to take my BP and found that its still high 161/77.I am wandering if my new doctor knows what he is doing.Any comments or suggestion? .Thank you
