This may cause weakness in the muscles of the hands and legs. I am glad that you are getting better. What has been recommended by your doctor is very important- physiotherapy and exercise.

Ensure that you strictly adhere to what they say and remember that healing will take time so don’t get tired of waiting.

Your phenotypes of headaches, gum pain, fear of death, panic attacks, stomach problems, and headaches after eating could be connected.

Weakness and sensitivity to light, as well as vomiting, may be the result of migraines. He is on paracetamol which is great, but he can also take the migraine medication his doctor prescribed if it is the case, even though it is soon after the paracetamol. It is important that the doctor’s guidance is adhered to and the medication is taken as instructed which will also help to prevent the next similar episode from happening.

Headaches can come from many different things. Sometimes it’s because you’re thirsty or you haven’t had enough to eat. Being stressed out or looking at screens for too long can also give you a headache. Drink some water, have a healthy snack, and take a break from screens. If the headache doesn't go away, seek medical help.

Bilateral hippocampal hypertension refers to raised pressure on both sides of the hippocampus in the brain. This can be unveiled by memory failure, headache, or seizures. At other times, high blood pressure is the usual cause. One possible solution is to change one's lifestyle to include a healthier diet and fewer quiet periods. Medications may also be recommended to bring the pressure under control and alleviate the symptoms.

The pain you feel could be caused by stress, not enough sleep, or even dehydration. Try to drink water, lie down in a calm place, and massage your temples gently. If it doesn’t go away or gets worse than before please consult with your doctor immediately.

As per the complaints, this is a case of Sinusitis.

If you have sinusitis, the doctor may be able to recommend additional medications to relieve your symptoms, such as steroid nasal sprays or drops to reduce sinus swelling.

antihistamines - if your symptoms are caused by an allergy

Antibiotics - if you have a bacterial infection and are severely sick or at risk of consequences, antibiotics may be prescribed (but antibiotics are often not needed, as sinusitis is usually caused by a virus)

I recommend taking the medication as prescribed to you by your doctor. But if you experience any side effects from it or want to go for some other treatment, you can talk to your neurologist. He will suggest some other treatments based on your condition like lifestyle changes, CBT or acupuncture etc. Also, follow-ups is must.
