Gastroenteritis, commonly referred to as stomach flu, is an inflammation of the stomach and intestines that can lead to a variety of symptoms, including nausea, vomiting, diarrhea, abdominal pain, and fever. It can be caused by viral infections (such as norovirus or rotavirus), bacterial infections (like Salmonella or E. coli), or parasites. In your case, it seems that you may be experiencing a viral or bacterial gastroenteritis, especially given your symptoms of fever, vomiting, and abdominal discomfort.

The symptoms you described, such as shaking, fever, and vomiting, are indicative of a systemic response to an infection. When the body is fighting off an infection, it can lead to a variety of symptoms as the immune system activates. The fact that you experienced a brief improvement before your symptoms returned after eating suggests that your gastrointestinal tract is still sensitive and may be reacting to food intake, which is common in cases of gastroenteritis.

The hiccups you are experiencing could be a result of irritation in the diaphragm or esophagus, which can occur with gastrointestinal distress. This can happen when the stomach is inflamed or when there is increased pressure in the abdomen due to bloating or gas. The discomfort in your stomach and the urge to vomit can also be attributed to the ongoing inflammation and irritation of the gastrointestinal lining.

To manage your symptoms, here are some recommendations:
1. Hydration: It's crucial to stay hydrated, especially if you are experiencing vomiting or diarrhea. Drink clear fluids such as water, broth, or oral rehydration solutions. Avoid caffeinated or alcoholic beverages, as they can worsen dehydration.

2. Diet: When you feel ready to eat, start with bland foods that are easy on the stomach, such as bananas, rice, applesauce, and toast (often referred to as the BRAT diet). Avoid fatty, spicy, or heavy foods until your symptoms improve.

3. Rest: Allow your body to recover by getting plenty of rest. Your immune system needs energy to fight off the infection.

4. Medications: Over-the-counter medications like anti-nausea medications (e.g., ondansetron) may help alleviate vomiting. However, it's essential to consult with your healthcare provider before taking any medications, especially if you have ongoing symptoms.

5. Monitor Symptoms: Keep an eye on your symptoms. If you experience severe abdominal pain, blood in your stool, high fever, or signs of dehydration (such as dizziness, dry mouth, or decreased urination), seek medical attention promptly.

6. Follow-Up: Since you mentioned that your symptoms have persisted, it may be beneficial to follow up with your healthcare provider. They may recommend further testing to rule out other potential causes of your symptoms, such as a bacterial infection that may require antibiotics.

In conclusion, gastroenteritis can be a challenging condition to navigate, especially when symptoms fluctuate. By focusing on hydration, a bland diet, and rest, you can help your body recover. However, don't hesitate to seek medical advice if your symptoms worsen or do not improve, as timely intervention can prevent complications.
