I've been congested, coughing and it's normally just my sinuses or allergies acting up which is resolved by Zyrtec right away. But, not this time. I've been sick for 3 days. I'm having flu-like symptoms like fatigue, chills and body aches, but no fever. I've been taking occiloco cinum, using nasal spray and cough drop. Do I need to see a doctor if this doesn't get better by tomorrow? FYI, as much as possible, I use natural remedies.
