Brain and Spine Problems

I can't remember what exactly happened in the last year when someone also I'm not sure Wt happened exactly .if I'm trying to remember then I'm getting headache and I'm feeling tired too so can u say me what exactly happening to me.

Past 2 days onwards my mother suffering from head roaming, vomits, body pains,can't able to stand properly because of dizziness and head roaming.she gets vomits after having liquid/food.past 3 months back she had an ear infection, at those times she used to have headaches.

Are neurological system and nervous system the same thing? If not, could you please clarify in layman terms?

My sister had Typhoid then a UTI in March, April beginning. After that since last 10-12 days she has been getting a pulsating headache behind her right eye. The pain is unbearable for her. Also at times while sleeping she feels that her right arm goes numb. She also has developed a distaste towards bright light & loud sound. Her RTPCR came negative thrice, CRP & d dimer values were normal, chest x-ray clear, so that kind of rules out Covid. During her Typhoid treatment she was given medication of Norflaxacin which later on in her urine culture showed that she was resistant to it. She was given this for 2 days via IV. Could it be a side effect of the medicine? We don't have anyone in our family with migraine history. How to know if it's a migraine? Please help us. For last 2 months we are very worried for her.

From the last 5-6 months I am suffering with headache when some one speaks loudly or when I speak loud when I lose my temper.Even when I am in deep sleep and if some one  speaks near me I lose my sleep.In the initial days I felt headache on the forehead but nowadays I am even feeling the ache at the back of my head mainly when I lay down to sleep on the floor.

From last few days my legs, area near knees is burning, below foot. Also, seems some numbness on calf.

13 month old seems to be doesn't have much concentration or eye contact, doesn't respond to name, less smile use parent hand as tool for doing something.  However he plays well, eats well, sleep well, loves to play peek a boo, loves tingling, Rome around house to search mother, showed to child specialist he said he is too small for any diagnose. Will he show any improvement before 18 months if not then why cannot we start any required treatment soon why to wait till 18 months?
