    Patients will receive paracetamol 1 gm every 6 hours daily intravenously for a day.

    Drug: Medical Treatment

  • Experimental
    Sphenopalatine block

    Patients will receive sphenopalatine block

    Procedure: Sphenopalatine Ganglion Block

Interventions

  • ProcedureSphenopalatine Ganglion Block

    Sphenopalatine Ganglion Block will be performed by a transnasal approach. Few drops of lidocaine 2% will be instilled into both anterior nares. Then a cotton-tipped applicator soaked in 4% lignocaine \& adrenaline (1 to 200000 will be passed through both the nares and the end of the applicator tip will be positioned just superior to the middle turbinate and anterior to the pterygopalatine fossa and sphenopalatine ganglion for 5 min with the patient in the supine position.

  • DrugMedical Treatment

    Patients will receive paracetamol 1 gm 6 hours daily intravenously for a day. If adequate pain relief will not be achieved, intravenous diclofenac 75 mg twice daily will be added.
