<s>[INST] Hi, I am having this feeling choking up when I lie down Fromm the last seven day I am 23 weeks pregnant. My O&G tried me on Nexium but thats not helping. I am also taking Claratyne. I also start coughing up when this problem starts. I am also using pillows but nothing helps. [/INST] Hi, I have gone through your problem. Are all your blood reports within normal limits as might have been explained to you by your Obst.& Gynae. doctor. It is advisable not to laydown straight while lying down, instead try to lie on your sides, left side is preferable during pregnancy as lying down straight puts pressure on underlying vessels. Sometimes low haemoglobin level may cause difficulty in breathing. It will be advisable to consult a chest physician to exclude any respiratory problem.You can do steam inhalation two-three times a day, avoid cold drinks and ice-cream, continue with the medicines prescribed by your doctor. Wishing you good health. </s>
