<s>[INST] I am constantly making a em em sound somewhat under my breathe, my husband says I do it all the time. Female, 58 years old, finished chemo Feb 28 for rectal cancer, had surgery last summer. I have a colostomy and I think it might have started as a coping mechanism to get used to changing the bag, but not sure. Also have RA and degenerative disc problems. I am taking Ativan, Zoloft, tramadol, methotrexate (for last 2 months), hydroxycloriquine. [/INST] Welcome in Chat Doctor. I understand your query as you said you are a follow-up patient of rectal cancer and having sound while breathing. Here I would like to say that unwanted breathing sounds are produced whenever there is either swelling, phlegm or obstruction in airway. Whenever these sounds are heard only during sleeping hours we call it as snoring. As a rule all above may be either in nose or throat. Different clinical conditions may be-1- Deviated nasal septum.2- Chronic Maxillary sinusitis.3- Nasal polyps.4- Turbinate hypertrophy.5- Thick and slag soft palate.6- Short neck with double chin.7- Loose para pharyngeal soft tissue. All above may be easily ruled out by clinical examination by an ENT doctor and may be managed accordingly. Thanks for consulting Chat Doctor. </s>
