Can i wrap my tibial lower leg stress fractures?

I have been diagnosed with bilateral stress fractures in my lower right and left tibias. My doctor said i needed to be booted, but if e decided to place boots on both of my legs, i would become miserable. He then ordered me 4 weeks of physical therapy. I am approaching my second week. I am having pain in the middle of my tibia on my right side. I was wondering if it would be okay to wrap my leg with an ACE bandage, or wear a compression sleeve to help support my bone. Also, I am 16 years old, i go to a very big school, and have to walk the halls and climb many staircases along with a 20lb. backpack. Can i wrap my legs? especially during the school day. PLEASE HELP.
