If the shoulder pain is unbearable after a fever, the following treatment measures can be taken: 1. The patient should first brake the shoulder and ensure adequate rest. At this time, the patient can use a scarf to suspend the forearm in front of the chest and keep the elbow joint flexed at 90 degrees. At this time, the patient must not use the affected shoulder to generate force to avoid further injury. Patients can also apply some self-heating materials to the shoulder, such as baby warmers, to provide a hot compress.2. Take oral medication that activates blood stasis, reduces swelling and pain, such as blood circulation and pain capsules or Yunnan Baiyao capsules.3. After doing the above treatment measures, patients need to go to an orthopedic clinic as soon as possible to clarify the cause of this symptom. For example, in this case, it may be due to inflammation of the shoulder after a fever, or due to an upper respiratory tract infection complicated by rheumatoid arthritis or other diseases. If the inflammatory reaction is clearly present, you can continue the above treatment and take oral non-steroidal drugs such as Nimesulide for treatment. If rheumatoid arthritis is clearly present, further anti-rheumatic and immune modulating treatment is needed in addition to the conventional anti-inflammatory treatment.
