There is no special ointment for rotator cuff injury, and the ointment is only used as auxiliary treatment. Rotator cuff injury can be caused by strain, trauma, degenerative lesions, etc. The treatment ointment is mainly divided into anti-inflammatory and pain relieving drugs such as diclofenac sodium and blood circulation and blood stasis activating drugs such as Nanxing Pain Relieving Ointment. For chronic injuries such as strain injury and degenerative lesions, the use of ointments such as diclofenac sodium and flurbiprofen and topical ointments such as Nanxing Pain Relieving Ointment and Pain Relieving Paste can effectively relieve pain. For acute injuries such as impact or sprain, if there is no wound on the skin surface, all of the above medications can be used; if there is a break on the skin surface, topical ointment may deepen the wound, and ointments such as flurbiprofen or ketoprofen gel are appropriate. If the rotator cuff injury is accompanied by significant pain and decreased flexibility in upper limb activities, it is recommended to seek medical advice as soon as possible, complete the relevant examinations and then use the medication under the guidance of the doctor.
