I finally broke down and made an appointment to see my doctor. I have now had this cold with cough since the first week of January. I have already done 10 days of antibiotics and there has been little change.
Yesterday I started having trouble with my blood glucose levels. They were at 198 in the morning, which is very high. My glucose level then crashed in the afternoon to 72 (very low). The low level caused uncontrollable shaking of my hands and made me feel light-headed. This is usually sign of an infection, so I am getting it checked.
