Smoking for 10 years is a sure shot factor for causing some type of respiratory disease. These are diseases like chronic bronchitis
. It is possible that you get symptoms of cough with blood because of this. Drinking alcohol can cause a disease called Mallory weiss. This is where you get retching
and then you can get tears in your esophagus
. I recommend you consult a doctor or a gastroenterologist.
The pain on your sides is most likely just muscle pain
due to running daily. You should get a proper warm up before running in order to be able to run without pain. I hope this helps. Do rate me if you found the information helpful.
