Since your blood pressure of 90/50 is normal for you, please stay well-hydrated. You can continue taking paracetamol (Crocin) to manage the fever and cetirizine (Cetrizine) as needed. Rest is crucial right now. Please consult your doctor for a routine follow-up to review your recovery, and seek immediate medical attention if you experience chest pain, shortness of breath, or extreme weakness.

Your increasing left-sided headaches could indeed be linked to eye strain from worsening eyesight, as your eye muscles work harder to focus. Additionally, frequently using Crocin (paracetamol) can sometimes lead to 'rebound' or medication-overuse headaches. Other possibilities include migraines, which typically affect one side. I recommend scheduling an eye exam to check your vision. It is also important to track how often you take paracetamol and consult a doctor. They can help safely manage your pain and identify the exact cause to bring you lasting relief.

Fever with cough, diarrhoea, cold, and shivering may be due to an infection and needs proper care. Take rest, drink plenty of fluids or oral rehydration to prevent dehydration, and eat light food as tolerated. You can use mild medicines for fever and symptoms if advised, but avoid taking multiple medicines on your own. Consult a doctor to assess your condition, especially as there are multiple symptoms and you may need specific treatment.

Since Crocin (paracetamol) isn't helping, they could try an anti-inflammatory medication like ibuprofen, as long as they have no stomach or kidney issues. Adequate hydration with water and electrolytes is incredibly important, as dehydration worsens headaches. Resting in a quiet, dark room with a cool compress on their forehead can also bring some relief. Please ensure they consult a doctor for personalized advice. If they experience alarming symptoms like neck stiffness, confusion, or high fever, they should seek immediate medical care.

It is very common for the heart rate to increase when the body is fighting a fever; the heart naturally beats faster to help pump blood. Since his oxygen levels are normal and he has no other symptoms, this is likely a normal physiological response. Please ensure he gets plenty of rest and stays well-hydrated. You can continue giving paracetamol (Crocin) to manage the fever as directed. However, if his heart rate remains elevated even after his temperature returns to normal, or if he develops shortness of breath, chest discomfort, or extreme fatigue, please seek medical attention.

Your symptoms suggest a viral infection, which usually improves with rest and supportive care, and Crocin can help reduce fever and body pain. Antibiotics like Clavam are not always needed unless there is a confirmed bacterial infection, so avoid continuing them without proper advice. Stay well hydrated, take light meals, and get adequate rest to support recovery. If symptoms persist for more than a few days, worsen, or you develop breathing difficulty, consult a doctor for further evaluation.
