Electro Homeopathic Treatment of Cold: Symptoms of a cold can be felt about 1-4 days after catching a cold virus. They start with a burning feeling in the nose or throat, followed by sneezing, a runny nose, and a feeling of being tired and unwell. This is the period when you are most contagious — you can pass the cold to others — so it’s best to stay home and rest.
