Diclofenac 1.5% Topical Solution 150ml: Effective Relief for Osteoarthritis, or Too Risky?

I've been prescribed Diclofenac 1.5% Topical Solution for my osteoarthritis. I've been looking at the side effects and I'm a bit worried. Has anyone had any issues with this topical NSAID? It says it can cause severe reactions and I don't know if it's worth the risk. I've seen some reviews saying it works great, while others say they had serious problems. Here's the long list of possible problems I've been reading about: Signs of an allergic reaction: rash, hives, itching, red, swollen, blistered, or peeling skin (with or without fever), wheezing, tightness in the chest or throat, difficulty breathing, swallowing, or talking, unusual hoarseness, or swelling of the mouth, face, lips, tongue, or throat. Signs of bleeding: vomiting or coughing up blood, vomit that resembles coffee grounds, blood in the urine, black, red, or tarry stools, bleeding from the gums, abnormal vaginal bleeding, unexplained bruises that enlarge, or uncontrollable bleeding. Signs of high blood pressure: severe headache or dizziness, fainting, or changes in vision. Signs of kidney problems: inability to urinate, changes in urine output, blood in the urine, or sudden weight gain. Signs of high potassium levels: irregular heartbeat, confusion, weakness, lightheadedness, dizziness, numbness or tingling, or shortness of breath. Skin irritation, chest pain or pressure, rapid heartbeat, shortness of breath, significant weight gain, or swelling in the arms or legs. Weakness on one side of the body, speech or thinking difficulties, balance changes, facial drooping, or blurred vision. Extreme fatigue or weakness, flu-like symptoms, or severe back pain. Severe Skin Reactions: Red, swollen, blistered, or peeling skin, red or irritated eyes, sores in the mouth, throat, nose, eyes, genitals, or skin. Fever, chills, body aches, shortness of breath, or swollen glands. Other Possible Side Effects: Dizziness or headache, constipation, diarrhea, stomach pain, upset stomach, or vomiting, gas, or heartburn.
