[|Human|] Hi, I am a 19 year old female and I have had a swollen lower back for the last six months. The swelling is directly superior to my sacrum and coccyx and proximal to the lower lumbar vertebrae . I have not gone to get it checked out, because I am trying to save money and it is not painful unless I over-excersize or do something to bother it. If i do that then I get a strange numbness in my quadriceps and extreme back pain to the point where i can hardly stand or even move at all. Any ideas to what it is? I am very confused and have studied up a lot, because i was a medical student for a while.
[|AI|]  Hello Adela ;welcome to Chat Doctor You need to get examined the swelling on your lower back to find the reason as to what it is. Asyou said the swelling is painless till you exert but on exertion it causes severe pain and numbness in muscles thereby suggesting that there is some relation to your spine as there is numbness which is due to nerve compression. Waiting long can complicate your problem and may require more money. So please get examined and treated by an Orthopaedician. Thanks
