A vague pain at a point on the upper right side of the back may be due to frozen shoulder and physiotherapy; it may also be due to fasciitis, which can be treated with bioelectricity and other physical and medication treatments. 1. Frozen shoulder: physical therapy such as hot compresses and infrared rays can be given to relieve the discomfort. In daily life, we should pay attention to keep the body warm and avoid lifting heavy objects, so as not to aggravate the condition. 2. Fasciitis: Physiotherapy, such as localized hot compresses, microwave, bioelectricity treatment, etc. can be used. If the pain worsens, you can take non-steroidal anti-inflammatory drugs, such as ibuprofen and other drugs under the guidance of a doctor. Such drugs have adverse reactions such as nausea, vomiting and allergy. If the symptom of hidden pain on the right side of the back is not relieved, or accompanied by other uncomfortable symptoms, you should go to the hospital in time, after clarifying the cause to give targeted treatment.
