Many people with joint pain like to put their arthritis hat on, and there are quite a few misconceptions. The first is the site, it must refer to inflammation within the joint, joint pain can also be due to pain caused by muscles or tendon membranes outside the joint, that kind cannot be called arthritis. The second is the cause. Arthritis can be caused by aging, immunity, infection, or gout, and there are strict diagnostic criteria for each type of arthritis. The third is treatment. Many people want to use antibiotics when they think of inflammation. Aging, immune caused by damage caused by what we call sterile inflammation, this time can not use antibiotics, only when there is an infection, you can use antibiotics.
