Sorry to hear that you feel so sick all the time,if it has been going on for some time,I think that a visit to your GP is indicated ,if it is a recent symptom ,is it something you are taking(eg.medication) or the like.Please visit your Dr. that is what he is there for,and as you have discomfort in your chest,that also should be addressed.It would be a brave person who would attempt any sort of diagnosis on this site,but a Dr. will have some answeres for you. Good luck,hope all will be well.
