Hi, I have a health question about my father. He is 56 years of age. He is having feet swelling, foot color change like a darkish brown/black color, & also a really bad odor along with it. He does not have a history of heart problems. He also is experiencing body & muscle aches along with this. Under the circumstances I hate to say this but it's true he is a heavy smoker & he is an alcoholic. He has been both for most of his life. Does the addictions he have could be the reason he is experiencing these health issues? Thanks for your cooperation.
