<s>[INST] My 20 year old son is recovering from what appeared top be pneumonia. He had a chest xray and blood test a few days ago and everything looked normal. However, he continues to have bouts of difficult breathing, a feeling of chest heaviness and poor circulation in his extremities. It is bedtime and he can t sleep because of his breathing difficulty. Is there something I can do for him? Do we need to go to the emergency room? [/INST] Hello rearward welcome to Chat Doctor.come have evaluated your query for your son in details .* It does not mean that normal chest x-ray stamps there is nothing inside.* He has underlying obstructive disorder involving bronchi or alveoli, must take to ER for further work up of pulmonary function test, CT thorax or others according to the clinician concern.
