A baby's skull bones do not fuse together totally until he is about a year and a half old. Until then a fontanelle or soft spot can give important clues to your baby's health. Seek immediate medical help if the soft spot is sunken, as can be seen in dehydration, or if it is bulging, as may result from trauma or infection.
While the list below can be considered as a guide to educate yourself about these conditions, this is not a substitute for a diagnosis from a health care provider. There are many other medical conditions that also can be associated with your symptoms and signs. Here are a number of those from MedicineNet:
Dehydration is the excessive loss of body water. There are a number of causes of dehydration including heat exposure, prolonged vigorous exercise, and some diseases of the gastrointestinal tract. Symptoms of dehydration include headache, lightheadedness, constipation, and bad breath. Treatment for dehydration is to replace lost fluids and electrolytes.
Abuse, Trauma, and Mental Health
Suffering abuse and trauma can put one at higher risk of developing PTSD, anxiety, and depression. Signs and symptoms of abuse or trauma include appetite or mood changes, alcohol and/or drug abuse, difficulty sleeping, and anger. Treatment may incorporate a combination of medication and talk therapy.
Abscessed Tooth Guide
An abscessed tooth is an infection within a tooth that has spread to the root. Symptoms of an abscessed tooth may include pain, swelling, tenderness, redness, and the presence of a pus-filled lesion on the gum. A dental professional diagnoses an abscessed tooth and dental X-rays may be required. An abscessed tooth is treated with a root canal.
Cysts are sac-like structures that may be filled with gas, liquid, or solid materials. Cysts may produce symptoms and signs depending on their location. Treatment of a cyst depends upon what caused the cyst in the first place.
