At your age, severe arthritis or blocked blood vessels are quite rare. However, muscle tension, TMJ issues, or a mildly pinched nerve in your neck can certainly cause grinding noises, tightness, numbness, and ear pressure. This is very common and highly treatable. I gently recommend scheduling an appointment with a primary care doctor or a physical therapist. They can perform a simple physical exam to find the exact cause and help you find relief.

These symptoms, especially religious rumination and concentration difficulties, are often associated with anxiety or a form of Obsessive-Compulsive Disorder (OCD) sometimes called scrupulosity. It is very common for these to impact focused tasks like studying while leaving daily routines untouched. A highly effective management strategy is Cognitive Behavioral Therapy (CBT), specifically Exposure and Response Prevention (ERP). Sometimes, a healthcare provider may also recommend selective serotonin reuptake inhibitors (SSRIs) to help. I highly encourage you to speak with a mental health professional who can guide you gently.

At your age, a common cause for a burning sensation radiating upward, paired with shortness of breath and dizziness, can be severe acid reflux or a sudden anxiety or panic episode. Dehydration or intense physical exertion can also trigger this. While these are often manageable, sudden chest discomfort and breathing difficulties always require immediate evaluation. Please contact a healthcare professional or visit an urgent care clinic right away.

Depending on the root cause, selective serotonin reuptake inhibitors (SSRIs) like sertraline can help quiet unwanted thoughts, while non-stimulant medications like atomoxetine or stimulants like methylphenidate can improve concentration. Combining medication with cognitive behavioral therapy (CBT) is often highly effective. I gently encourage you to speak with a healthcare professional or psychiatrist.

The best time to conceive is during your 'fertile window'?the five days leading up to ovulation and the day of. You don't need to completely cut out tea or coffee, but keeping caffeine under 200 mg a day (about one cup of coffee) is ideal. Riding a scooter or motorcycle is generally safe while trying to conceive, but please prioritize your safety to avoid falls. Once you get a positive pregnancy test, it is best to avoid riding due to the risk of injury.

What you are describing sounds like anal stenosis, a narrowing that can sometimes develop from scar tissue long after surgery. Please be reassured that this is treatable. For immediate relief from itching and pain, warm sitz baths and mild, over-the-counter hydrocortisone or lidocaine ointments can help. To safely address the narrowing, a doctor may recommend stool softeners, pelvic floor therapy, or gradual dilation. Sometimes, a minor corrective procedure is the best option. I highly recommend seeing a colorectal specialist to discuss these options and help you find lasting comfort.
