My husbands who is 46 years old, has a problem with his feet that often swells up. He went to the doctor, and they found vitamin d deficiany, which he started a course of medicine, and finished the course. Now, I noticed black patches on his ankles which almost look like dirt, but you cant scrub it off. Has anyone have a similar problem or know what this is due to? I am very concerned about this.
Thanks for your help!
