Painful lump on middle spine that is growing larger

Patient: Hi, approximately two months ago I notice a hard, non painful, pea sized lump on my spine about half way down my back. The lump has now at least tripled in size and has become very painful and the surrounding tissue has reddened. Also, I’ve noticed that it’s growing larger more rapidly than before. I’m also experiencing very bad headaches and I’m often waking in the middle if the night drenched in a cold sweat.

Symptoms: Head ache, cold sweats, middle back pain surrounding lump.
