Answer
Hello Lindsay,

Can you post a picture for me?  
What do you mean lumps on each side of his head?  
Can you tell me a little bit about the setup, that would help.  What type of substrate are you using, sand, tiles, paper towels?  Are you using an undertank heater along with a low wattage basking light on one end?
Are you leaving a small water dish in his tank too?
What foods are you feeding him?  Do you leave crickets in his tank for extended periods of time?  Are the lumps hard or soft?
