I had decompression 5 weeks ago. Since then i have a very big,, jelly feeling lump on head and have visited the ER. Surgern has said there is a leak inside it has not broken through the scar, there is a hole inside from surgery. They put compression bandage on, said that might fix it, after taking bandage of to shower, the lump was gone, still felt like jelly , then it came back bigger and it hurt 20 min later. Is this good i dont know, my neck is feeling very stiff and sore, i need some advice pleasee
