[|Human|] My lower back has a lot of swelling and pain, the one side of my buttons has quite a large lump in it. Also, I have now developed bad pains all through my legs which is causing me to have pain while walking. I went to the doctor and she said it was Cocydinia and gave me pain killers. That was last week and now the pain is worse than it was when I went there! What could this be? Should I get it checked again?
[|AI|]  Please mention whether pain is unilateral or bilateral and also character of pain. Handover in lump in buttock as u have mentioned, it can be compressive neuropathy and in this scenario USG of buttocks will help it can be lumbosacral radiculopathy causing articular pain. Do MRI LS spine. Try tab praline Hope my advice will help you.  Take care. Don't forget to rate me.  Analgesics for symptomatic relief.
