I am a marijuana smoker and recently I have just smoked. It isnt severe but I feel this pain in my lower chest area, right below my left rib. It has decreased over a span of time but it doesnt seem to be going away. I probably smoked about 2 hours ago.
Hello, I need to know more about the symptoms, like precipitating factors, factors that increase pain etc. There are two possibilities in you, one is gastritis and second is due to smoking.  Mostly it's a gastritis and reflux disease. Do you upper abdominal pain, nausea, bloating, burping, increase in pain on food, sour water feeling in throat or chest burning, if yes it further supports the diagnosis? You should avoid fatty, oily and high calorie diet. Have some walk after having food instead of taking rest. Have multiple small meals instead of heavy meals. Have regular sleep habits and avoid stress. Lots of green leafy vegetables, fruits. Avoid smoking and alcohol if any. You can get prescribed tab Pan DSR 40 mg before breakfast once a day for 2 weeks.  Secondly, it may be due to smoking, as it causes damage to lungs. This pain frequently but not always increases on deep breathing and coughing etc. Treatment is reducing the smoking and if hurting a lot then needs NSAIDs like ibuprofen 500 mg or diclofenac 50 mg on whenever needed basis. Get back if you have any doubts.
