For your shoulder pain, you can try over-the-counter oral pain relievers like ibuprofen or acetaminophen to reduce pain and inflammation, provided you have no contraindications. Locally, applying a topical non-steroidal anti-inflammatory gel, such as diclofenac gel, directly to the shoulder three to four times a day can offer targeted relief. Resting the joint and applying an ice pack for 15 minutes a few times a day will also help. If the pain persists beyond a week, worsens, or is accompanied by numbness, weakness, or neck pain, please consult a healthcare professional for a proper evaluation.
