I had my flu jab on Thursday, it still has a red oval shape around it but doesn't hurt, is this normal?
Not that uncommon: Without seeing and feeling it, it sounds like you just have some local irritation at the injection site, which is common with many different vaccines. As long as you don't have fevers, spreading redness, increasing pain, discharge at the site, you'll likely be fine. Consider cold compresses to speed resolution.

You "caught" the cold in the days before your shot. Good for you getting your flu shot. The full blown flu is a misery. ...Read more
