I am new to the forum and hope I can find some answers and see if anyone else has went through similar problems. I had a 2 part spinal fusion l4-l5 8 weeks ago. I have been doing everything the dr said. As you all know, no bending, lifting over 10 lbs or twisting. When I went to my second post op visit, I showed him the "lump" that was under my incision, about the size of a half baseball, he said it was a seroma, fluid build-up and that it was nothing to worry about, use heat and my body will absorb it. I am still having pain also, not like it was but enough to wear I am taking Norco and Soma. Some days my pain is about a 6-8. Now, I am 8 weeks postop and having days to where pain is worse and when I am hurting like that, my lower back is swollen more and not just on the incision but all the way across to the other side and extremely painful moving around. I am not able to do a lot around the house yet either. So, I am not over doing it. Mostly in my recliner with a firm pillow behind me to keep my back straight and supported and heat several times a day. I just don't understand why I am having more days that this swelling is happening.. any input would be greatly appreciated!
