Dextrose Hydrodissection for Post-Breast Cancer Chest Wall and Axillary Tightness.

The goal of this clinical trial (prospective case series) is to evaluate the feasibility, safety, and preliminary clinical outcomes of ultrasound-guided dextrose prolotherapy in female breast cancer survivors with persistent ipsilateral chest wall and axillary pain and tightness who have plateaued with standard physical therapy. The main questions it aims to answer are: Does ultrasound-guided dextrose prolotherapy significantly improve upper extremity functional limitation (measured by the QuickDASH questionnaire)? What are the effects of this intervention on pain intensity (NRS), active shoulder range of motion (AROM), and anterior chest wall soft-tissue tightness (pectoralis minor muscle length)? Participants will: Undergo a comprehensive baseline physical examination and ultrasound assessment of the symptomatic chest wall and axilla. Receive three sessions of ultrasound-guided 5% dextrose injections into targeted soft-tissue planes at 4-week intervals. Continue their designated standard rehabilitation program, including range-of-motion and stretching exercises. Attend follow-up assessments at 4-week intervals during the treatment phase, with long-term follow-up at 3 and 6 months after the final injection to evaluate the durability of the response.
