I am feeling pain at mid section of my chest from last 10 days and suddenly it has increased from last 2 days. Actually pain has started due to heavy cigarette smoking 10 days back after that pain reduced as i was smoking 1 or 2 cigarettes max. In a day. On Saturday i smoked heavily and the pain started again from morning when i woke-up, same continued yesterday and today as well. Last week on Tuesday hairline pain started on my left side neck to solder which still continues. I am worried that might i am suffering from TB or something bigger than that. Please help.
