A thyroid storm

Thyroid storm is a life-threatening condition that develops in cases of untreated thyrotoxicosis (hyperthyroidism). This is an emergency condition. If suspected, call 911 or another emergency number. A thyroid storm is usually brought on by stress such as trauma or an infection. Symptoms are severe and include agitation, change in alertness (consciousness), confusion, diarrhea, fever, tachycardia, restlessness, shaking, and sweating.

Increased facial movements

The primary Parkinson’s disease symptoms include tremors, muscle rigidity, bradykinesia (slowness of movement), and postural instability. These may be mild at first, but will gradually become more intense and debilitating. Facial movement decreases, resulting in generalized rigidity with masked facies.

Giardiasis

Giardia lamblia is a protozoan with flagella that infects the small intestine. Giardiasis is common in the developing world and rural areas and can cause acute and chronic infection. Campers, hunters, backpackers, and travelers to endemic areas are at highest risk. The incubation period is 7 to 14 days, and symptoms can last for 2 to 4 weeks. Chronic infection can result in malabsorption and significant weight loss. First-line antibiotics are tinidazole (Tindamax) or nitazoxanide (Nizonide). Alternative antibiotics are metronidazole (Flagyl) and others.
