Diabetic neuropathy or just an injury?

This morning I woke up with an unusually high blood sugar due to an over correction. I noticed that my middle toe on my left foot was hurting. I'm 25 years old- type 1 since age 7- my A1c is usually in the low 7's. I don't know if this is a diabetes related thing or an injury (I workout and wear heels often). My feet are not burning or anything- just this one toe. Is this worth getting tests done by my endo or nothing to worry about?
