Your daughter's symptoms are typical of cerebral palsy which causes a lack of muscle coordination and also results in mobility problems. Those symptoms you named are the cause of an extra motor diagnostic test to be done, like hip reflexes to be tested, and a tossed foot drop. The most optimal way is physiotherapy to do work on muscle tone or strength and loosen tightness, to let your child move properly. In the case of consistent therapy, she will grow more independent and be able to use her muscles more easily so she can join you in activities.

As your symptoms indicate, you may be suffering from a migraine or tension headache. But one should not exclude the possibility of serious conditions. I suggest consulting a neurologist for further detailed diagnosis. While you wait, work on reducing your stress and have a good sleep at night. Recall that your health should be considered first and you might need medical attention if the situation requires so.

Headaches can arise in many ways, for example, stress, lack of sleep, or even looking at screens for too long can cause them. It's better to lie in a peaceful place, drink a lot of plain water, and abstain from excessive screen time. If the pain persists, you need to go to a doctor and get a thorough checkup done.

Inhaling gas, taking alcohol and some drugs can be dangerous especially when coupled with lack of sleep and food. Symptoms such as headache and shivering might mean that your body is stressed. Take a rest, eat well, and keep off harmful substances.

Using tap water to flush your nose­ can be unsafe. Tap water may have­ bad germs. But, do not worry too much about it. Getting a brain infection from this is ve­ry rare.

These­ could mean infection. 

MND or Motor Neuron Disease is a severe disorder that causes damage to the nerve cells responsible for controlling muscles. MND patients have various treatment choices that are based on symptoms.

You may be wondering if you have an iron deficiency. Anemia is a condition that develops when your body does not have enough red blood cells to carry oxygen. This may result in fatigue and strange symptoms of dizziness and headaches. A decrease in appetite is another situation that is often found. Intake of green leafy vegetables like spinach, seeds high in protein like beans and lean meat may be helpful. Besides, your doctor may also bring up the consumption of iron supplements to improve your red blood cell count.

A spinal cord issue such as hers might result in weakness of stepping and the absence of the sense of touch. It occurs when the spinal cord sustains damage, generally from events such as a car ramming into it. Exercise makes muscles stronger, but full recovery might not be attained.
