Yes, physiotherapy can be helpful after removal of the cast for a 5th metatarsal fracture. After several weeks of immobilization, it is common to have ankle/foot stiffness, muscle weakness, swelling and difficulty putting full weight on the affected foot. Since your doctor has already permitted full weight bearing, rehabilitation can help you return to normal walking gradually and safely.
Next Steps
Consult a physiotherapist for assessment of pain, swelling, ankle/foot range of motion, muscle strength and walking pattern. Treatment can include gentle ankle and toe mobility exercises, progressive strengthening, balance exercises and gradual weight-bearing/gait training according to your tolerance.
Health Tips
Do not force full weight bearing if it causes significant pain. Increase the load gradually and use support temporarily if required. Avoid running, jumping or high-impact activities until adequate healing and strength have been achieved. If pain or swelling is increasing rather than improving, follow up with your orthopaedic doctor and consider repeat imaging as advised.
