Hello - thanks for asking your question.
GERD has many manifestations, which I will describe here.
The most common symptoms of GERD are heartburn (or pyrosis), regurgitation, and dysphagia. In addition, a variety of extraesophageal manifestations have been described including asthma, laryngitis, and chronic coughing. Heartburn is typically described as a retrosternal burning discomfort, radiating toward the neck. Regurgitation is the effortless return of gastric or esophageal contents into the pharynx without nausea, retching, or abdominal contractions. Patients typically regurgitate acidic material mixed with small amounts of undigested food.
GERD-related chest pain may mimic angina pectoris, and is typically described as squeezing or burning, located substernally and radiating to the back, neck, jaw or arms, lasting anywhere from minutes to hours, and resolving either spontaneously or with antacids. It usually occurs after meals, awakens patients from sleep, and may be exacerbated by emotional stress.
Globus sensation is the almost constant perception of a lump in the throat (irrespective of swallowing), which has been related to GERD in some studies. However, the role of esophageal reflux in this disorder is uncertain. One study suggested that globus was associated with a hypertensive upper esophageal sphincter rather than with reflux.
Water brash or hypersalivation is a relatively unusual symptom in which patients can foam at the mouth, secreting as much as 10 mL of saliva per minute in response to reflux, but can be seen in GERD.
GERD needs to be distinguished from gastritis, infectious esophagitis, pill esophagitis, peptic ulcer disease, non-ulcer dyspepsia, biliary tract disease, coronary artery disease, and esophageal motor disorders. Unexplained chest pain should be evaluated with an electrocardiogram and exercise stress test prior to a gastrointestinal evaluation. The remaining elements of the differential diagnosis can be evaluated by endoscopy or biliary tract ultrasonography.
The bottom line is that the symptoms that you have described can all be seen in GERD - however, you have to see your personal physician for a definitive diagnosis.

One more question, if it is a reflux problem, can it heal and not return? Or are the diet/lifestyle modifications I've been reading about permanent?
