There are several considerations regarding these symptoms.
The jaw symptoms that you describe are common in persons that have dysfunction of the joint of the jaw, called the temperomandibular joint, or TMJ. The TMJ is located immediately in front of the ear. The pain with TMJ dysfunction is frequently felt around the ear and radiates along the muscles that move the jaw, so can extend along the face or down the neck, as well as causing headaches. One of the risk factors for development of TMJ dysfunction is grinding the teeth. TMJ dysfunction is not usually associated with abdominal symptoms.
It is possible that the pain is due to an acute infection, which also can cause the chills, sweating, nausea, and diarrhea. The most common type of infection would be a viral infection, although a bacterial infection is also possible.
The hemorrhoid would be unrelated to these conditions, although the diarrhea may exacerbate the symptoms from the hemorrhoid.
Ultimately, it would require an appropriate evaluation to determine the exact cause, but there are some home interventions that you can try. It may help to take an over the counter anti-inflammatory medicine, such as ibuprofen or naproxen. It also may help to apply local care to the jaw, such as ice or moist heat. If these interventions do not help, then it would be appropriate to be seen at that point.
