Question: I had the flu a month ago. I no longer have a fever (feeling loads better) but I still have lingering Nasal Congestion and a cough. I was wondering when if/when I should schedule an appointment with a doctor or if I need to let the lingering symptoms run their course.

Brief Answer:
post viral cough can occur in some persons

Detailed Answer:
HI, thanks for using healthcare magic

Cough can persist for up to 6 weeks after the flu.
It is called post viral or post infectious cough

Nasal congestion can linger in some persons though this is more likely if there is a previous history of allergies

The use of a anti histamine decongestant combination may help both symptoms eg zyrtec d, allegra d, claritine d, benadryl d.
You can try using one of these for at least 10 to 14 days and see if this would help.

A topical nasal spray such as nasonex, flonase, rhinocort, may also help as well.

If there any worsening during this time period or no improvement after or you remain concerned, then you should be seen

I hope this helps, feel free to ask any other questions

Can Levolin Inhaler aggravate the viral cough? My son is 5.5 years and he has always been suffering from viral cough. He has severe cough at nighttime. Our doctor suggested Levolin inhaler on sos basis along with some cough syrup. But, immediately after we use the levolin inhaler, we find that the severity as well as the frequency of the cough increases, what might be the reason? is there any other solution we can have other than levolin inhaler.

I am having some gastrointestinal issues. In December 2011 I came down with a really bad sinus infection and viral cough. I was sick for about 9-10 weeks and was on 2 rounds of amoxicillin and an albuterol inhaler with steroids (I’ve had asthma since birth). Mid February 2012 I came down with sudden nausea. The first time it hit I got light headed, clammy, it felt like the blood drained from my body and I was going to vomit. This feeling persisted throughout the week and I went to the doctor. At the time I was in Germany for only another month and a half so they did a basic stool test which didn’t turn up anything. I was given anti-nausea and anti-inflammatory drugs. The nausea persisted and would hit a couple of days a week. I came to realize that coffee and alcohol seemed to be a trigger for the worst nausea. In April 2012 I was back in the states and was diagnosed with cryptosporidium via a more extensive stool test. I began a 5 month course of natural supplements and vitamins which also required me not to drink alcohol or coffee. By September I felt fine and was able to drink without issue, though I never pushed it being wary. At the end of the year I caught a cold and stopped drinking alcohol, I did not go on antibiotics. By January 2013 it was clear the nausea was still around, again it usually started having drank coffee or alcohol the day before. I went into the doctor again and was diagnosed with c. diff. I was on the corresponding meds (including trying 2 different antibiotics (to minimize induced nausea), Prilosec (symptom of previous) and 2 anti-nausea pills that didn’t really help) for two weeks. I was told to wait a few weeks to see if symptoms came back and they did. A blood test did not reveal anything other than elevated white cell count and my adrenals/thyroid were a bit off. I got a cold 3 days after the test so that is the most likely cause. I then had to go on Sudafed (OTC) and Cheratussin. The nausea has gotten better overall throughout this process but I still experience 1 day every 2 weeks of intense nausea even without drinking coffee or alcohol. The non-drink induced nausea usually occurs 1 hour after I wake up and lasts 1-2 hours being super nauseous (dry heaving into toilets and trashcans). Overall I am more tired + less focused (no coffee) and feel shittier in general having to deal with symptoms and the fact that I have no idea what’s going on. I moved to LA recently for grad school and the doctor I see at a downtown clinic is hard to get ahold of so I have no idea where to go from here. I am tired of feeling like shit all the time.
