Alternative treatments are safe for most people. However, some alternative treatments may cause side effects or allergic reactions. For example, some people are allergic to echinacea. Herbs and supplements may also change the way other medicines work. Talk to your doctor before trying an alternative treatment.

The fluid from your runny nose will become thicker and may turn yellow or green within a few days. This is normal, and not a reason for antibiotics.

Most cold symptoms usually go away within a week. If you still feel sick after 7 days, see your doctor to rule out a sinus infection, allergies, or other medical problem.

Colds are the most common trigger of asthma symptoms in children with asthma.

A cold may also lead to:

• Bronchitis
• Ear infection
• Pneumonia
• Sinusitis

Try treating your cold at home first. Call your doctor if:

• Breathing becomes difficult
• Your symptoms get worse or do not improve after 7 to 10 days
