I believe my cold is evolving into sinusitis since this morning (pain in the sinus on my left cheek, headaches, and toothaches). Should I see a doctor?

If you believe your cold is developing into a sinus infection, it may be a good idea to consult a healthcare professional. Sinus infections can cause pain in the sinuses, cheeks, as well as headaches and toothaches. While being pregnant, it is important to seek medical advice before taking any medication, including antibiotics. Using products like Sinus Rinse™ can also be helpful, but it is important to follow the recommended instructions for best results. If you have any concerns or questions, don't hesitate to reach out to a healthcare provider for guidance.
