my adult son is on prednisone prescribed by a pa and and antibiotic. He has what appears to be a sinus condition which caused his left eye to become swollen shut. It has been 30 hrs. since he was seen and the headaches have come and gone. Now he has pain in his rear teeth area and had a stiff neck but it has subsided. he toke asprin and that helped with the headache. He has on more day of the prednisone then he will have completed the prescription. the pain came back should he wait another day or seek treatment.
