I had an injury a month ago where I bruised my cocix (tailbone) bone.  Ouch.  The pain is gone at the end of my spine....but now I  feel a bulge just to the right of my tailbone.  Its not really painful (a wee bit) but noticed it while exercising this morning.   What might that be?
Hello, As per my clinical experience, the lump after injury suggests a hematoma formation. In our clinic, primary care with ice application, anti-inflammatory, and antibiotic medications are recommended with best results. Hope I have answered your query. Let me know if I can assist you further.
