Adjustments in Eyewear Prescription After Six Months
Greetings! I am a 20-year-old woman who underwent an eye examination today. The optometrist informed me that my new prescription reads 300 for my right eye and 275 for my left. Additionally, I have astigmatism and am curious if it is typical for an eye prescription to shift so significantly within a six-month period. For context, during my previous eye check-up, my prescription was 225 for the right eye and 175 for the left.

It's understandable to be concerned about significant changes in your eyewear prescription, especially within a short time frame like six months. Here's an overview of what might be happening alongside some practical steps you can take.
Key Points:
- Changes in your glasses prescription can happen, particularly at a young age.
- A shift from 225 to 300 in your right eye and 175 to 275 in your left is noteworthy and may be due to several factors.
- Astigmatism can also fluctuate, affecting overall vision clarity.
Explanation:
Your eyesight can change for various reasons, including normal developmental changes, changes in eye health, or increased strain on your eyes from activities like screen time. At 20 years old, your eyes might still be adjusting or adapting, which is common. However, a significant increase in your prescription does warrant attention, especially with your mention of astigmatism.
A couple of things that can influence changes in prescriptions include:
- Eye Strain: Increased screen time or poor lighting can strain your eyes.
- Health Factors: Conditions like diabetes or thyroid issues could impact vision.
- Genetics: Family history of vision issues can also play a role.
Next Steps:
- Follow the New Prescription: Start wearing your new glasses as prescribed, as they will help you see more clearly.
- Monitor Symptoms: Pay attention to how your vision feels with the new prescription. Notice if you're experiencing headaches, blurry vision, or discomfort.
- Limit Eye Strain: Take regular breaks when using screens, following the 20-20-20 rule—every 20 minutes, look at something 20 feet away for 20 seconds.
- Maintain Eye Health: Ensure you have regular check-ups (annually recommended) to monitor any further changes in your vision.
- Consider Lifestyle Factors: Evaluate your daily activities for potential stress on your eyes (like extended screen time or lack of rest).
If you continue to experience drastic changes or discomfort, it would be helpful to discuss these concerns thoroughly with your optometrist during your next visit. They can offer more personalized insights and adjust your care plan if necessary. Remember, taking care of your eye health is an ongoing process.

Understanding Bilirubin Level Fluctuations
I'm a 21-year-old female, standing at 151 cm tall and weighing approximately 40 kg. I don’t engage in smoking and only use allergy medications occasionally. After having some tests done, my general practitioner mentioned I'd receive a call if there were any issues with my pathology results. However, I did not get a follow-up call. Out of curiosity, I took a look at my health records and noticed that in 2025, my bilirubin level was recorded at 25 umol/L, while the latest measurement shows it has risen to 37 umol/L. The reference range indicates that normal bilirubin levels should be between 0 and 20 umol/L. Should I be concerned about this increase?

Experiencing Symptoms Post-Appendectomy: Should I Consult a Doctor?
Two days ago, I (15M) started feeling quite nauseous, and later, I developed a fever. The following day, I was hit with stomach pains I've never felt so intensely before. Although it still isn't unbearable, it does sting when I touch that specific area. Given that the discomfort is localized where my appendix used to be, it raised some alarms for me. I eventually decided it might just be due to constipation and attempted to ease the situation. Just an hour ago, I managed to have a bowel movement, and now the pain is only noticeable when I press on that spot or while walking. Do you think this warrants a trip to the doctor?
The Challenge of Trusting Medical Care
Female In my 40s Last summer, I contracted COVID-19, which sent my body and mind into turmoil. My anxiety skyrocketed due to the pain I was experiencing, exacerbated by the disbelief from medical professionals who insisted my symptoms were merely in my head. Despite numerous trips to the emergency room, it wasn't until the fall that a doctor finally discovered something significant after conducting scans without contrast. I also experienced a concerning episode with a friend, which included a sudden headache accompanied by dizziness that lasted for a couple of days. Miraculously, after that incident, many of my concerning symptoms began to ease. Yet, I remain in the dark regarding what exactly was afflicting me. By January, I started a new medication but unfortunately had an adverse reaction. They performed a contrast scan to rule out any serious medical issues, and that’s when they uncovered a previously unrecognized condition that should have been identified earlier. This isn't the first instance where my diagnosis was overlooked, remaining absent from my records until another healthcare provider brought it to light. I have no intention of pursuing legal action. Pain medication isn’t my priority either. What I desire is improvement within the system—an assurance that my statements about my health will be taken seriously and that I will be informed of any diagnoses affecting my wellbeing. I often feel as though I'm slipping through the cracks, unable to access the care I so desperately need. How can one maintain faith in a system that consistently disappoints?
Loss of Sensation in My Leg
I am a 22-year-old female, weighing 125 pounds. For the past month, I’ve been experiencing a strange sensation on the left side of my knee; the skin in that particular area has become completely numb. While I retain full mobility in my leg and can perform regular movements, I cannot feel anything when I touch or scratch that specific patch of skin—it’s as though it’s lost all sensation. Additionally, I don’t wear any tight-fitting clothing that might cause this issue. I am uncertain about the potential causes of this numbness.
