###Human: What is the reason for the feeling of windpipe compression in a pregnant patient? ###Assistant: Hello. We are happy to help you. I understand your situation and the worries the problem might be causing to you, that too when you are pregnant.  With the symptoms you have described, and with the doctor's repeated reassurances to you, I feel there may not be any super significant physical finding that they might have missed. That being said, there is nothing wrong in getting a proper specialist referral from the GP. I do not understand why the GP is reluctant to do that. If you were to come to me, I will do a nasal endoscopy in OPD (office) and do a flexible fiberoptics laryngoscopy also in the office. These two require no special medication except for decongestion of the nose and local spray into throat and passing of endoscopes. These will rule out sinusitis, DNS (deviated nasal septum), nasal disease and also laryngeal problems, say growth, vocal cord changes, movement of vocal cords, pyriform fossae, etc.  I do not anticipate anything in these areas, but these two tests will conclusively rule out any issue there. Maximum what I expect is some allergy and allergic post nasal drip. This will get alright with some nasal sprays which will not get absorbed into the bloodstream and will not cause any issue to the baby. Looking at the pictures (attachment removed to protect patient identity), regarding the undersurface, it Is normal to have that color. The veins underneath look so. The color of the palate and posterior pharyngeal wall do appear mild pale and bluish. We need to rule out anemia in you and also allergy. Allergy and nasal discharge and post nasal drip can cause these discolorations. Reflux can also be spotted in laryngoscopy, however, the Ranitidine should solve the matter nevertheless.  What I want to know is the exact duration and chronology of all your problems. How many weeks pregnant are you? Has hemoglobin been checked? Are your scans normal? Why the Aspirin and blood thinner? Can you show me the relevant prescription? Any past history of sinus disease or nose block or post nasal drip or allergy? Sneezing, running nose, reduced sense of smell, itching, watering of eyes, etc.? Do revert back to me with relevant details. You should feel better soon. Do not worry.
