How do I differentiate between normal post-op pain vs pain from another herniated disc? I ask because last night I had excrutiating pain on my left side. It went from my incision, over to the left, and wrapped around my left side along my ribcage. It was extremely painful, and I ended up having to take my stronger pain meds. It's so easy to chalk everything up to healing after spine surgery, but at what point does it become concerning? The discs I had operated on were herniated to the right. However, I have another disc that is herniated to the left that he did not touch, because it hasn't caused me any symptoms. When I had the intense pain last night, it left me wondering how do I know at this point? Obviously I'm going to have pain as my muscles continue to heal from the surgery, but how do I know what's normal and what's not? Or how do I know when to call the surgeon or wait it out?
