I have been having an extremely dry mouth for the past six weeks. My lips and entire mouth go dry especially at night in bed and the pain is very bad when it wakes me up. My mouth is very dry and even sticks to my teeth. My throat is sore as well and I am having trouble trying to swallow food when I eat. I am 65 years old. A male. I have not seen a doctor in the past three years for a check-up. I am now on Medicare. Thank you
