<s>[INST] Hi, I have been unwell for some time now and my primary symptoms are; constant phelgm needing to be cleared from back of throat which is worse after lying down for lying periods. I get abdominal pains after lying down for long periods such as at night. I get left leg pain from buttocks to knee when sitting down and have an alomost constant nausea feeling which again seems to worsen after lying down. Also from time to time get left chest pains. Regards. [/INST] Hi. Thanks for your query. Your history is full of unrelated symptoms.TO elucidate: you have pain in the throat, constant phlegm needing to be cleared, which is worst after lying down. This indicates that you may have sinusitis so that on lying down position the secretions of the sinuses travel down to the throat to cause the problems you have. Your abdominal pains too start on lying down as well as you have left leg pain from buttock to the knee increasing in lying down position. Both the things together suggest that there may be a problem with the intervertebral discs compressing on the cord. I would advise you the following.:MRI of the spine. Contrast enhanced CT scan of the abdomen, with angiography if required. Diagnostic Laparoscopy if required. </s>
