hi. noted history of severe pain on big toe. based from your description, it is possible that you have an inflammation/infection secondary to an ingrown toenail. this usually happens after a pedicure or when your toenail is accidentally cut wrongly. it may also be a recurrence of your fungal infection. it is best if you consult with a doctor for physical examination and clinical evaluation. management (medical and/or surgical if indications are found) will be directed accordingly. good hygiene and avoidance of manipulation over the affected area are also advised. hope this helps. good day!! ~dr.kaye
