@bjcobb I also recently had SI Joint surgery. I experienced pain in my arms as well. I attribute this to using a walker. Have you also been prescribed a muscle relaxant. I found that taking Flexeril first thing in morning and last thing at night along with my pain meds really helped. Force yourself to move around and walk with your walker about every hour as well. I was prescribed 1-2 Percocet 0.5 mg every four to six hours but called surgeon because I was no getting relief and he told me I could take three if needed. This was only for the 3 days post op. I am three weeks post op now and find the pain considerably diminished. Maybe once or twice a week i need to take 1 Percocet for pain. Hope this helps. This surgery has changed my life. No more throbbing pain all the time You will get there. Good luck

@bjcobb Hello BJ, Marc here. I had a Lumbar Spinal Fusion done at L5-S1 about 3 months ago. Like you, I did not have major pain at the surgery site, but less than two weeks after the surgery I was getting the pain you describe as feeling on fire in my legs, from my hips to my ankles. This happened every evening, starting around 7pm and went all night. After four nights of this, I asked my wife to drive me to the ER to find out what I could do.

Long story short, I was prescribed Lyrica for my legs. My surgeon's PA wrote me a prescription for 75mg capsules to take three times a day. I took one capsule when I woke up, one around lunch, and the third about 6pm. This helped almost immediately, as the second night on the medication, I slept most of the night without the fire in my legs. A side-affect for me was actually sleeping better than I had in months.

Ask your doctor about Lyrica for your pain and see what they recommend. Good luck!
