I m a 63 year old female with Type 2 Diabetes. For the last 5 or 6 days, I ve had a deep cough and for a few days had chills and woke up in the mornings with a damp pillow and t-shirt. The chills and sweating are gone, but yesterday and today my arms feel shaky. I saw a doctor on Saturday who gave me tessalon pearls and told me to take benedryl. He said I did not have a fever. I ve been taking the pearls and benedryl as directed, but I don t notice an improvement in the cough. Can you tell me if I should be using different meds or doing something other than what I m presently doing.
