For Tendonitis "I went to the doctor after having pain in my elbow. I thought it was tennis elbow, but my doctor dismissed it as tendonitis and quickly prescribed me Naproxen 500 mg to be taken twice daily. I made sure I took it after food, and on the third day in, I started experiencing stomach pain and indigestion/heartburn. This continued over the next 2 days with increased pain and feeling bloated. On the fifth day, stiffness started creeping in all over my body, so bad that I couldn't take my own clothes off. It is now day 6. I haven't taken any tablets and had to spend the day in bed. It has even made my breasts feel very sore. I feel as though I've been in a horrendous car crash. I will definitely not be taking this drug ever again. I'm usually a very fit 49-year-old."

For Tendonitis "I had a severe side effect of naproxen. I had some inflammation in my left knee, and it was bothering me when sitting down, so I showed it to the doctor. I was prescribed naproxen 500 mg twice a day for 5 days. I took three tablets in 36 hours (making sure after lunch and dinner and with plenty of water), and after taking the second pill on the first day, I had a terrible time. I couldn't sleep, had a severe funny feeling in my stomach, right under my ribs and just above the stomach. I had a strong empty-stomach feeling all the time. The feel for my whole body was terrible, and I felt super sick. I didn't throw up or have loose motions, but I had lots of stomach pain and extreme heartburn. I stopped taking the medicine after 3 pills and informed my doctor."

For Back Pain "I am pretty sure this medication is just acid in pill form. And not the fun kind either. No. I took this medication for severe arthritis and fibromyalgia, and 15 minutes later my whole esophagus feels like it's on fire. I took the medication with food as prescribed, and still, this is the worst heartburn I have ever had in my life. I used to have severe ulcers, and I know when a medication is burning my stomach lining. No sir. No more ulcers for me, thank you. I also had the alarming sensation of hearing everything while underwater. I spent the whole week asking people to repeat themselves because their voices sounded muffled. That with severe ringing in the ears and persistent nausea - I quit this medication after a week."

For Pain "So far, so good for chronic neck pain/spasm. It's the first time I've tried it, and my neck has never felt better. The only side effect has been mild heartburn, but I'd rather that than not being able to move my neck."

For Osteoarthritis "I’ve been taking these naproxen on and off for years relating to joint pain. Most prominent in my back, feet, and knees. I’ve finally said enough is enough. I might as well be popping candy. They are a complete waste of time. I get zero benefit from them but am fortunate that I don’t get any side effects, with the exception of heartburn. I know several people that take them, and no one can say in my circle they are a benefit to them. I’ve now had to resort to Nurofen Plus, which financially is crippling, but they at least give me some very mild relief."

For Tendonitis "Was prescribed drug for Achilles tendinitis, 500 mg Naproxen twice a day with omeprazole 20 mg. Should never have taken this as it caused heartburn and stomach infection, stopped taking on the second day and still have not recovered from stomach problems over 2 months later despite taking other remedies. Disgusting drug!!!"

For Osteoarthritis "Omg. What a horrible drug. I was prescribed this along with lamproserol to ease my osteoarthritis pain in my upper back. I only took them for three days. It gave me the worst heartburn ever and terrible acid reflux. I will never take them again."
