I have had a dry cough for two weeks after a cold. What could be going on?
A dry cough lasting two weeks after a cold is commonly seen and can have several possible causes.
Possible causes
- Post-infectious cough: After a viral upper respiratory infection (common cold), cough can persist as the airways remain irritated. This is often called post-viral or post-infectious cough and usually improves over time.
- Subacute cough: Defined as cough lasting 3-8 weeks, often due to residual inflammation from infections like bronchitis or pertussis.
- Cough variant asthma or atopic cough: Sometimes airway hyperreactivity after infection can cause prolonged dry cough.
- Sinobronchial syndrome or sinus-related cough: Post-nasal drip from sinus inflammation can cause cough.
When to see a doctor
- If you develop fever, shortness of breath, wheezing, or cough with sputum.
- If cough lasts longer than 8 weeks or worsens.
- If you have other concerning symptoms like weight loss or night sweats.

Five tools in one app.
Pick a tool when you start a chat, and DoctorAI adapts to the question.
-
Symptoms, medicines, side effects, or what a word on your discharge letter means. You get a calm, sourced answer at any hour, and you can keep asking follow-ups in the same chat.
-
Snap a photo of your blood work or upload the PDF. DoctorAI goes value by value through CBC, cholesterol, thyroid, vitamin and liver panels, shows which numbers are out of range, and lists questions to take to your doctor.
-
A rash, a cut, a swelling, a strange spot after an afternoon in the garden. Take a photo and get a plain-language look at what it could be, most likely first, and which signs mean someone should see it in person.
-
X-ray, MRI and CT reports are written for other doctors. DoctorAI reads yours systematically and explains each finding, so you walk into your appointment knowing what to ask.
-
Exam-style clinical vignettes with step-by-step reasoning and a verdict on every answer choice, not just the right one. Or ask it to explain a concept the way a good tutor would.
