I had decompression surgery 5 weeks ago. After getting my stichers out, there was a lage lumpnext to the stitchers. We just thought it was swelling, It had not gone by week 4 it felt like jelly and it was incomfortable to lean on anything and it was getting bigger, Went to hospital, had ultra scan done and they found a leak from the inside, a small hole, They decided to put compression bandage on. The lump went down , was still like jelly, and after it was of for 30 mins, it seemed to come back and my head is hurting more then normal, I would like to know why this is happening and should i be worried.
