Welcome to 55: Welcome to 55. There are multiple possibilities; evaluate if this is a "new" phenomenon for you. However, suffice it to to say you are in a great deal of excellent company. Not a rare occurrence. Until you can be seen by either your Primary Care Physician or an Orthopedist you can safely apply cool compresses (never apply ice or cold compresses directly to skin) 15 minutes twice daily.

55 the old 35: You shouldn't be experiencing these symptoms at 55 unless there has been some history of previous trauma or disease. You need a hands-on physical examination, X-Ray and possibly an MRI.
