The pain in deltoid muscle for several months may be caused by cold, muscle strain, tendon strain, frozen shoulder and other reasons.
1. Exposure to cold: If the patient lives or works in a cold and damp environment, the deltoid muscle will be exposed to cold, resulting in poor local blood circulation, metabolic abnormality and muscle dysfunction, causing pain.
2. Muscle strain: If the patient engages in heavy shoulder labor for a long time, it will easily lead to cumulative damage to the deltoid muscle, resulting in muscle strain and thus pain.
2. Tendon strain: If the patient strains the tendon of deltoid muscle during strenuous exercise, pain will occur.
3. Frozen shoulder: prolonged overwork or trauma to the shoulder joint area will easily damage the soft tissues around the shoulder joint, such as ligaments and muscles, forming aseptic inflammation. The phenomenon of deltoid muscle pain may be caused by the stimulation of inflammation.
The deltoid muscle pain for several months may also have other causes, it is recommended to go to the hospital in a timely manner, improve the examination to clarify the cause of the disease, under the guidance of the doctor to give targeted treatment or treatment.
