"I have a cold and I feel crackling?"

It sounds like you may have a nasal congestion or runny nose, which could be caused by sinus secretions dripping into the throat. I would recommend practicing nasal hygiene with a saline solution like Hydrasense or Sinus Rinse. You can use it as often as needed throughout the day and at least 30 minutes before bedtime. Drinking plenty of fluids, whether cold or hot, can also help alleviate your symptoms. Hope this information is helpful, and feel free to reach out if you have any other questions.
