I am 38 years old, male have had no heath issues untill now. I quit smoking but today is only my 5th day, quit any type of soda for about 2 months now. Eating better and exercising have lost about 32 lbs. Feeling bad for 3 weeks now but this week the worst, i am convinced I have lung cancer. I have pain in right shoulder, light headed dizzy spells, hand look pale and get tingly as do my feet, fatiguied, cant sleep and wake up with bad night sweats, i am scared to death. I have an appointment at 10;30 today but really nervous and scared.
