<s>[INST] I am experiencing constant phlem with cough for 2 months.  Causes me to not sleep, also get dry mouth and difficulty breathing.  My primary care physician gave me an inhaler with limited results.  My cardiologist did a ultrasound of my heart which showed no problem (past history of congestive heart failure).  He recommended increasing my Lasix to reduce swelling with limited results.  My Polmonologist said my lung capacity is weak.  He wants me to take a sleep apnea test for sleep problem and a CATSCAN to get more detail on my lungs.  I am concerned whether I am going down the right path but right now I am just grasping at straws for a cure.  Thoughts? [/INST] HIThank for asking to HCM You have given incomplete medical history, important things your age and sex are missing, these the only important things in medical, without this it is difficult to say any thing, any way this could be respiratory syndrome, without any apparent etiology and may go away it self, have nice day. </s>
