Could my symptoms indicate a brain disease?

You may have a tension headache. This headache feels like a tight band around the head and can cause vomiting. Common causes for these headaches include stress and tension, poor sleeping habits, or eye strain from looking at screens too much. To alleviate your symptoms, you should take some non-prescription painkillers such as acetaminophen or ibuprofen. Additionally, get enough rest and drink plenty of water while trying relaxation methods like deep breathing exercises or light workouts. If they don’t go away or get worse it would be best if you visited your doctor so that he could give them proper attention.

Setting a proper sleep schedule and reducing screen time are good steps, but sometimes additional help is needed. Since the neurologist's treatment didn't suit you, I recommend visiting a sleep specialist. They can provide personalized advice and alternative treatments to improve your sleep.

It seems that you may have this condition called palpitations. You may feel that your heart is beating fast or irregularly in your hands, stomach, or legs in this case. Anxiety, stress, too much caffeine, or a lack of sleep may sometimes contribute to this issue. Relax, keep away from caffeinated drinks, sleep well, and visit your family doctor if you feel potential disturbances.

Bell’s palsy is a condition where facial muscles on one side of the face are not functioning properly, thus causing the affected part to droop. Smoking or vaping can make your recovery take longer. These kinds of practices can be a good reason to avoid them when you are sick because more time your body requires to recover.
