For Pain "I have been given no other choice but to self-medicate! I have a spot on my brain and a cyst on my brain stem and in my spinal column, in my neck from a car wreck that gives me intense pain, as well as headaches where I feel I would be better off dead and gone than to suffer while... no doctor in Kentucky will help, to them, everyone is a junkie! Which is just WRONG... I suffer to where a grown man sits and cries! So I will do what I have to do for pain relief! It helps when a man really needs it! I know I am not the only one!"

For Chronic Pain "I have had headaches, both migraine and just normal head pain since I was very young. I'm 56 now. I have tried several pain meds for my day-to-day, all-day headaches, from plain aspirin to what I'm on now, morphine sulfate. I'm only 'allowed' to take 5 mg every 8 hours. This single pill does not work.... My doctor is on notice, not sure what for, but because he is, he had to cut me down from 25 mg to the 5. The higher dose was working!!! I'm now in pain again. Over the years, I've gone from aspirin, Tylenol, ibuprofen (works sometimes, extra strength, times 4-6 liquid caps), oxycodone, etc., etc., but morphine works for me!"

Morphine for Chronic Pain "I have been using Kadian for at least 9 years now. I haven't ever had the need to increase dosage, unlike Oxy, etc. My pharmacy wholesaler stopped carrying Kadian a few months ago, and I have been sick ever since. Headaches, loose bowels, and G.I. distress. I am searching for Kadian without much luck."

Morphine for Pain "This medicine claims to be 24-hour extended release, but it is not. It releases the total dose within an hour. This is not an effective generic equivalent to Avinza 24-hour ER or Kadian 12 SR or Kadian 24-hour ER. The pain control is not effective or consistent. The side effects are severe and dangerous. I had a severe headache daily, liver enzymes elevated, no appetite, severe nausea, caused chest pain and shortness of breath."

For Chronic Pain "I have severe chronic low back and pelvic area pain. I take four 10 mg oxycodone and one 15 mg morphine a day. What I don't understand is why the 15 mg morphine gives me headaches, but the 30 mg morphine doesn't. How do I get my Dr. to understand? I would rather be given a quantity of 15 30 mg morphine than a quantity of 30 15 mg morphine."

Morphine for Pain "They say this form of morphine is resistant to being abused, which basically just means that it makes you feel like complete garbage. Worst headache of my life. If it is not broke, don’t fix."
