It is not unusual to experience symptoms like ringing in the ears (tinnitus) and sensations of small electric shocks in the head when discontinuing certain medications like Cymbalta. These symptoms can be exacerbated by stress and are usually temporary. It is recommended to consult a doctor if the symptoms persist or worsen, especially if the medication has already been stopped. It may be helpful to go back to the lowest dose that alleviated the symptoms while weaning off the medication.
