<s>[INST] Hello doctor, Five years ago, I quit smoking. I am a 34 year old male, who weighs 220 lbs. I had health anxiety and had asthma tests, ECG, EKG, and chest x-rays done. I drank fairly often for four years. The last three months, the frequency picked up, and I was getting really drunk. Over the four years, since my tests, I have smoked roughly a pack of cigarettes total. I completed three marathons in three months last year. My son was born two months back, and my running slowed to almost a halt (3 to 10 miles a week max). I am not getting back in shape, and I am attempting a 365-day running streak and quitting alcohol for that time as well. Last week, I did 16 miles and this week I did 20. I had a tight chest last week and went to the urgent care. EKG results were normal. After running now, I seem to have a sore back and slightly tight chest. I do not have to gasp for air, but it seems as if breathing is labored. When I take a deep breath, my chest and back feel sore. Also, I have OCD. Is this just getting back into shape? [/INST] Hello. Hope this helps you, and get back if you have any doubts. For more information consult a cardiologist online --> </s>
