Costochondritis usually does not cause itchy skin, mainly with rib pain, for infectious costochondritis can also be accompanied by fever and other conditions. Most cases of costochondritis are caused by trauma, overwork and other factors that lead to local aseptic inflammatory reaction, also known as non-specific costochondritis, which is mainly manifested by localized pain, such as localized dull pain, tingling or burning pain. Generally, the condition can be clarified during MRI examination and treated with oral non-steroidal anti-inflammatory and analgesic drugs such as acetaminophen and diclofenac sodium. Infectious costochondritis is mainly caused by localized infection due to bacteria and other infectious foci, resulting in pain, fever, swelling, etc., but it is rarely accompanied by localized itching of the skin.
