You should consult a doctor or physiotherapist who can guide you through gentle stretching and strengthening exercises to improve movement and reduce stiffness. Regularly moving your shoulder, using heat therapy, and taking pain-relief medication, if needed, can help ease discomfort and prevent further stiffness. In some cases, your doctor may recommend steroid injections to reduce inflammation and support faster recovery.

Please see a doctor for a proper examination, as knee pain with swelling and difficulty walking may indicate a serious injury, infection, or inflammation. You may take paracetamol or ibuprofen for pain, keep your knee elevated, apply a cold compress to reduce swelling, and avoid putting weight on it until it has been examined.

Your wife should see a doctor promptly for a thorough evaluation, as severe pain with a burning sensation may indicate an underlying medical condition. Do not give her any medication on your own. Keep a record of her symptoms, pain levels, and any changes in her mood or behaviour to help the doctor find the appropriate treatment.
