Given your fever, severe headache, and recent red eye, we should consider a few possibilities since your dengue test was negative. These symptoms, especially when not responding to standard antibiotics, could point towards certain viral infections like adenovirus, or other infections such as leptospirosis or rickettsial diseases, which can cause eye redness and headaches. I strongly recommend visiting your doctor promptly for specific blood tests to get an accurate diagnosis. Please stay well-hydrated, rest, and use paracetamol for comfort while seeking an in-person evaluation.

Since your cough is worsening and your fever of 101?F has persisted for two days despite taking Crocin (paracetamol), it is important to see a doctor for a proper evaluation. A physician can listen to your lungs to rule out any secondary infections. In the meantime, please rest, stay well-hydrated with warm fluids, and continue paracetamol as directed. Avoid starting any antibiotics without a prescription. Please seek immediate medical care if you experience any shortness of breath, chest pain, or if your fever rises further.

Experiencing distorted smells and tastes is called parosmia, is actually a common sign of recovery after viral infections like COVID-19. The good news is that for most people, it improves over time as the nerves heal. A highly recommended, safe approach is olfactory training. You can do this at home by sniffing strong, familiar scents like lemon, eucalyptus, rose, and clove for 20 seconds each, twice a day. This helps gently retrain your brain's connection to your senses. Please be patient with your body, and consult a doctor if you need further support.

Crocin, which contains paracetamol, temporarily reduces your temperature but doesn't treat the underlying infection. Your recurring mild fever, combined with a loss of taste for five days, strongly suggests a viral illness, such as COVID-19. Please rest, stay well-hydrated, and consult a doctor for a formal evaluation or test. These symptoms are very common and highly manageable.

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.

Because you are vomiting, the Crocin (paracetamol) you took may not have been fully absorbed by your body. For now, try to take tiny, frequent sips of water or an oral rehydration solution to stay hydrated, and use a cool, damp cloth on your forehead to help lower the fever. Since the vomiting is preventing you from keeping medication down, I highly recommend consulting a doctor. They can prescribe a generic medicine to stop the vomiting, allowing the paracetamol to do its job safely.
