Neither cold therapy nor heat therapy is recommended in the clinical guidelines for treating frozen shoulder. There’s limited evidence and little rationale to support the use of either modality in managing the condition. Frozen shoulder is a condition that typically resolves over time, with or without these treatments. Neither cold nor heat therapy will speed up the recovery process, but both may offer temporary relief for some patients, depending on their individual response. Once proven treatments—like patient education, structured exercise, and regular monitoring are in place, patients can experiment with hot or cold therapies to see which offers symptom relief. Ultimately, the choice between the two should be based on personal preference and how each therapy makes the patient feel.
