[|Human|] i have a golf ball sized lump inside my back to the right of my spine in my lower back. the area around it its soft where on the otherside of my back its hard (like theres bone there) Its very painful at times and not painful at others. I can gently move the lump around in small circles. my right side is swollen. About 2 months ago i injured my sciatic nerve but there was no lumps in my back.
[|AI|]  Thanks for your question on Chat Doctor. In my opinion, you should consult orthopedic doctor and get done 1. Clinical examination of swelling 2. Ultrasound examination of swelling 3. MRI of lumbosacral spine. Since you are having sciatic nerve injury in the past, following are the possible complications which can give rise to such swelling. 1. Menimgocele 2. Meningomyelocele 3. Neuroma of sciatic nerve All these needs surgical correction as all are enlarging in nature and can cause future complications if left untreated. So consult orthopedic doctor and discuss all these.
