56 year old male 6'3" 225lbs slightly overweight. Dermatologist diagnosed psoriasis. Prescribed Taclonex, Dermasmooth, .2 Hydrocortisone. Go tanning despite Dr and PA advising against it. They advocate using their booth. Tanning booth works infinitely better. So here is my problem: Seem to have recently developed persistent cough. Went to urgent care. Chest X-ray negative. Coughing seems to be associated primarily with consuming liquids or laughing while sitting. Any thoughts or comments appreciated. Have family members who are RN and Chiropractor. Tremendous respect for those in medical field.
