50 Secret Signs You are Sick

As a doctor, I know that it’s not always obvious that you are ill. Sometimes symptoms and signs can creep up on you. You just aren’t sure whether to bother people like me. Remember: You’re not a hypochondriac; you’re looking after yourself! If you suffer from anything on this list, your doctor will be pleased to see you and relieved you made that appointment!
