A muscle tear or strain in the hand can take several weeks to heal completely, especially if the injury is moderate or severe. Even after 15 days, some pain and discomfort can still be present, but the pain should gradually improve over time. Since your hand is already in a plaster cast, it is important to keep the hand well-rested and avoid putting pressure or strain on it. Keeping the hand elevated on a pillow while resting can help reduce swelling and discomfort. For pain relief, medicines such as paracetamol or anti-inflammatory medicines may help if advised by your doctor, but they should not be taken continuously without medical supervision. Applying ice packs around the affected area for short periods during the first few days after injury can reduce swelling, while gentle heat therapy may help later once swelling decreases. Eating a healthy diet rich in protein, calcium, vitamin D, nuts, milk, eggs, pulses, fruits, and green vegetables may support muscle healing and recovery. Some doctors may also recommend supplements like calcium, vitamin D, or protein supplements if needed. After the plaster is removed, physiotherapy and gentle hand exercises are very important to regain strength and movement. However, if the pain is severe, worsening, associated with numbness, swelling of fingers, discoloration, fever, or inability to move the hand properly, you should revisit your orthopedic doctor because further evaluation may be needed to rule out a deeper muscle, tendon, or ligament injury.
