I have red eyes, congestion, sneezing, & trouble sleeping/very tired. this happened few weeks ago and ended up with sinus infection. should i see dr?

Yes: If you continue with symptoms beyond about a week despite over the counter medications like tylenol, (acetaminophen) rest, and hydration you should see your doctor again. Viral infections may sometimes turn into bacterial infections, requiring antibiotics. Sometimes allergies can mimic a sinus infection and need prescription medications to help.
