Frequent Sneezing, Congestion, Itchy Rash or Chronic Cough — Not Always Just a Cold
Many people experience sneezing, a blocked nose, a runny nose, an itchy rash or an on-and-off chronic cough and assume it is just a common cold. In reality, these can be signs of an allergy, one of the most common health issues in both children and adults.
Allergies are becoming more common worldwide, including in Thailand. Environmental factors, air pollution and changing lifestyles may all play a part.
Although allergies are not contagious, leaving them chronic or frequently flaring can affect quality of life, sleep, study and work.
