i am only 33 years old and my joints are achy and my knees make grinding noises when i walk up stairs. I am physically fit and exercise 4x a week. What could be going on?
I'm sorry but this is outside our area of expertise. Do you have Migraine in addition to achy joints? I really want to help you with an answer to your question, but can't, because it cannot be adequately answered online. A diagnosis can only be provided by a doctor who can review your medical history, your family's medical history, discuss your symptoms, and conduct a complete exam in person.
I can send you over to the ChronicPainConnection.Com and see if they have any answers for you.
