What's my ailment? please help?

i've posted this in health category but there's still no reply. i'm desperate for an answer so i posted it here. here goes. i'm in a foreign country away from my family. i'm in my early 40's. medium built. doing 50 push-ups every other day. been here for 7 months now. smoking at least average of 10 sticks a day but gradually removing it out of my system (guess it's too late). i started feeling pain in my right ribs 4 months ago and i thought it was only muscle pain or the weather then (8 degrees C) and it was tolerable then. i haven't had any accident. then the pain escalates now to the point that i cried and i'm shouting in my pillows because i don't want to be heard by my co-workers adjacent to my room. i don't want to go to hospital for fear that the result will lead to my early retirement. i couldn't afford to go home early because of our present economic plight (i still have to pay a lot of debts back in my home country and my family still needs remittance) and i'm almost sure that the result would be serious. recently, sores on my right ribs appeared and the pain is almost unbearable especially on nighttime. i virtually could not sleep when it attacks at least thrice a week. i could still work though, in each and every attack. just tell me what's causing this pain. professional opinion please. i really don't want to go to a hospital. and i'm ready to endure this. i just want to know what is it or better yet, how much time do i still have. thank you.
