Neck, shoulder, and back pain after exercise is usually due to muscle strain; rest, gentle stretching, and warm compresses can help recovery. You may take a pain reliever like Paracetamol or, if suitable, an anti-inflammatory like Ibuprofen for short-term relief, and apply a topical gel such as Diclofenac gel. Avoid heavy workouts for a few days and restart gradually; if pain is severe, persistent, or associated with numbness or weakness, consult a doctor.

For temporary relief of shoulder pain, you can apply a topical generic diclofenac gel or a menthol-based ointment directly to the joint. For oral pain relief, generic ibuprofen or acetaminophen can help reduce discomfort and inflammation, provided you have no underlying stomach, heart, or kidney issues. Resting the arm and applying an ice pack for 15 minutes can also ease symptoms. Since this is your left shoulder, please seek immediate medical attention if the pain is accompanied by chest tightness, shortness of breath, dizziness, or sweating. Otherwise, consult a doctor if the pain persists beyond a few days.

Pain above the back of the knee during movement is often due to a mild hamstring strain or tendon irritation. For targeted relief, you can apply a topical generic diclofenac gel or a menthol-based ointment to the area three to four times daily. If needed, short-term oral pain relievers like paracetamol or ibuprofen can help reduce discomfort, provided you have no medical contraindications. Additionally, try resting the leg, applying ice wrapped in a towel for 15 minutes, and avoiding strenuous movements. If you experience severe swelling, redness, or the pain does not improve within a few days, please consult a healthcare professional for a proper evaluation.

Swelling and pain in the joints, especially in the knees, with difficulty sitting or bending, can happen due to arthritis, inflammation, age-related wear and tear, uric acid problems, autoimmune conditions, or sometimes vitamin deficiency and weight-related stress on the joints. Since the swelling is affecting daily activities like sitting on the toilet, it is important to get it properly evaluated rather than only using painkillers repeatedly. The best specialist to consult would usually be an orthopaedic doctor if the problem seems mainly related to the knees and movement, or a rheumatologist if there is long-term stiffness, swelling in multiple joints, or suspicion of inflammatory arthritis like rheumatoid arthritis. For temporary relief, doctors commonly use anti-inflammatory medicines, pain relievers, supportive knee exercises, and sometimes calcium or vitamin supplements, depending on the cause. Warm compresses, avoiding excessive stair climbing, reducing body weight if overweight, and using a western toilet temporarily can also reduce strain on the knees. Since long-term swelling can damage the joints gradually, it is better to get examined early so the exact reason can be identified and the treatment can be planned properly instead of only controlling pain temporarily.

For knee osteoarthritis, treatment focuses on relieving pain and improving mobility. Initially, topical pain relievers like diclofenac gel are highly recommended as they have fewer side effects. For oral medications, acetaminophen is a safe first choice, while oral NSAIDs like ibuprofen or naproxen can be used short-term for stronger inflammation. If these do not provide enough relief, joint injections can be very effective. These include corticosteroid injections to rapidly reduce swelling and pain, or hyaluronic acid injections to help lubricate the joint. Please consult your doctor to find the safest and most effective combination for your specific health profile.
