You have work restrictions but you have not mentioned if this is from workers compensation, short term disability or somthing else.  If it is merely a doctor's note, it may not qualify under much of anything.  Under the Family Medical Leave Act (if you and your employer qualify), you would or could take up to three months off of work without pay. Check with your state labor department regarding your particular rights.  In terms of whether it is appropriate, it may not be but violative of your rights, probably not.
