The pain has a significant impact on activities of daily living especially as those affected live in fear of when they are going to get their next attack of pain and how severe it will be. It can lead to severe depression and anxiety.However, not all people will have the symptoms described above and there are variants of TN. One of which is atypical trigeminal neuralgia ("trigeminal neuralgia, type 2" or trigeminal neuralgia with concomitant pain), based on a recent classification of facial pain. In these instances there is also a more prolonged lower severity background pain that can be present for over 50% of the time and is described more as a burning or prickling, rather than a shock. Trigeminal pain can also occur after an attack of herpes zoster. Post-herpetic neuralgia has the same manifestations as in other parts of the body. Herpes zoster oticus typically presents with inability to move many facial muscles, pain in the ear, taste loss on the front of the tongue, dry eyes and mouth, and a vesicular rash. Less than 1% of varicella zoster infections involve the facial nerve and result in this occurring.Trigeminal deafferentation pain (TDP), also termed anesthesia dolorosa, or colloquially as phantom face pain, is from intentional damage to a trigeminal nerve following attempts to surgically fix a nerve problem. This pain is usually constant with a burning sensation and numbness. TDP is very difficult to treat as further surgeries are usually ineffective and possibly detrimental to the person.
Multisystem inflammatory syndrome in children (MIS-C), or paediatric inflammatory multisystem syndrome (PIMS / PIMS-TS), or systemic inflammatory syndrome in COVID-19 (SISCoV), is a rare systemic illness involving persistent fever and extreme inflammation following exposure to SARS-CoV-2, the virus responsible for COVID-19. MIS-C is also recognized as a potential pediatric adverse event following COVID-19 vaccination. It can rapidly lead to medical emergencies such as insufficient blood flow around the body (a condition known as shock). Failure of one or more organs can occur. A warning sign is unexplained persistent fever with severe symptoms following exposure to COVID-19. Prompt referral to paediatric specialists is essential, and families need to seek urgent medical assistance. Most affected children will need intensive care.All affected children have persistent fever. Other clinical features vary. The first symptoms often include acute abdominal pain with diarrhoea or vomiting. Muscle pain and general tiredness are frequent, and low blood pressure is also common. Symptoms can also include pink eye, rashes, enlarged lymph nodes, swollen hands and feet, and "strawberry tongue". Various mental disturbances are possible. A cytokine storm may take place, in which the childs innate immune system stages an excessive and uncontrolled inflammatory response. Heart failure is common. Clinical complications can include damage to the heart muscle, respiratory distress, acute kidney injury, and increased blood coagulation. Coronary artery abnormalities can develop (ranging from dilatation to aneurysms).This life-threatening disease has proved fatal in under 2% of reported cases. Early recognition and prompt specialist attention are essential.
