I've been prescribed Morphine Sul 8mg/ml Inj, 1ml for severe pain, but I'm really nervous about the side effects. I've read the list, and some of them are quite scary, like serotonin syndrome and allergic reactions. Has anyone else experienced these? How did you manage? I've also seen some posts about spinal injections having additional side effects. Can anyone share their experience with that? I'm just trying to be prepared and know what to look out for.

This stuff is no joke. I've seen people get really out of it on morphine. Be careful and listen to your doctor.

I had a spinal injection of morphine and ended up with muscle spasms and loss of movement. It was horrible to see. They had to adjust the dosage and she recovered, but it was a nightmare. Be very cautious with that method.

I've been on morphine for a while now, and the side effects have been manageable. Just watch out for the constipation—it's a killer! Stay hydrated and consider a stool softener. Also, don't drive or operate heavy machinery until you know how it affects you.

Wow, I had no idea morphine could cause so many side effects. I'm glad I'm not on this stuff.

I had a bad experience with morphine too. I ended up with severe constipation and had to spend a few days in the hospital. It was miserable, and I had to switch to something else after that. Be careful with this one!

My mom had a spinal injection of morphine and ended up with muscle spasms and loss of movement. It was horrible to see. They had to adjust the dosage and she recovered, but it was a nightmare. Be very cautious with that method.

I had a bad reaction to Morphine once. It was terrifying. I ended up with severe itching and hives all over my body. Went straight to the ER. I think I was lucky, it could have been much worse. I would recommend having someone with you when you first take this stuff just in case.
