What you are describing isn't really clear. So, the short answer is yes, you need to see a doctor. The skin change may be important. IF it comes and goes, be sure to get a picture. There are some blood tests that your doctor may want to do, but they need to be placed in the context of other symptoms and the skin change may be important. The important concern in your diet, beyond controlling weight, is the amount of sodium (common salt) that you take in every day. Acceptable is Exercise should be anything that is aerobic, repetitive and maintained for longer than 20 minutes. Exercising every day should be your goal. No matter what you do with diet and exercise, stop smoking.
