Your heart rate increases suddenly in situations such as hearing a slight sound or starting work, as part of a normal ?fight or flight? response triggered by adrenaline, which temporarily speeds up your heart rate. If it happens frequently or is accompanied by dizziness, chest pain, or shortness of breath, please consult your doctor to rule out heart rhythm problems or other underlying issues.

You should consult a doctor or urologist to identify the underlying cause, which may include stress, depression, hormonal imbalances, or medical conditions such as diabetes or heart disease. Treatment may include medications, such as selective serotonin reuptake inhibitors for rapid ejaculation or testosterone therapy for low libido, along with counselling and lifestyle changes to improve sexual stamina and desire.

You should use a toothpaste containing desensitising and antimicrobial agents, such as potassium nitrate or stannous fluoride, to help with both sensitivity and swollen gums. Brush gently with a soft-bristled toothbrush to avoid further irritation. If the swelling persists or worsens, please see your dentist promptly.
