Hi, Duality . . . I would suggest making an appointment with an ear, nose and throat specialist. You may have some sort of infection going on that your doctor is not catching but if she believes the ear wax is no big deal, it may not be. It would just be good to get a second and a specialist opinion.
First of all, nose bleeds are often aggravated by blowing your nose hard, dry air and being around irritants (smoke and dust, for example). I would suggest especially now with winter coming on that you run a humidifier in your room at night. You should drink plenty of fluids so that you keep hydrated internally. Also, if you can handle it, try a light coating of Vaseline just inside each nostril morning and before bed time.
As for the ear wax, our only winter heat is a wood stove. My ear wax turns orange (that may be what color yours was) just because pollutants tend to get into our ears as well as getting into our respiratory system.
Tell the ear, nose and throat doctor about what you are experiencing. They are better equipped to diagnose you and recommend treatment.
Let us know how it goes!
