certain medical information is treated as highly confidential. This does not really sound like it falls under that catagory. (Generally limited to HIV related info). If your supervisor was cc'ing other employees who needed to know, such as his manager and some sort of attendance tracking assistant, there may be a legitimate reason to share that information. Sharing medical information with a larger group might be more problematic, especially if there was no reason to do so. You should not be afraid of retaliation for contacting HR. That is their job. Retaliation is illegal. You may not have a case right now but you certainly might if you were retaliated against. Talk to HR.
I agree with the wise observation of Mr. Swedlow. Retaliation is illegal. Do not fear it. Get an attorney to keep your employer with the proper perspective.
