[37M] Experiencing fever, headache, and sensitivity to light

What might be happening

Based on the information you've provided, possible diagnoses include:

• Infection: Given the persistence of your fever for 13 days, an ongoing infection is a possibility. The fact that you're on doxycycline, an antibiotic, suggests that your doctor may have suspected this. However, if your symptoms have not improved, the infection may not be responding to the antibiotic, or the initial diagnosis might have been incorrect.

  • Treatment for infections typically involves antibiotics or antiviral medications, depending on the cause of the infection.

• Meningitis: This is an inflammation of the membranes surrounding your brain and spinal cord. It's usually caused by a viral infection, but bacterial, parasitic, and fungal infections can also lead to meningitis. Your headache, sensitivity to light, and difficulty concentrating could be symptoms of this condition.

  • Treatment for meningitis varies depending on the cause. Bacterial meningitis can be life-threatening and requires immediate antibiotic treatment. Viral meningitis often resolves without treatment, but severe cases may require hospitalization.

• Drug-induced fever: Some medications, including antibiotics like doxycycline, can cause a drug fever. This is a fever that occurs without any signs of infection after starting a new medication.

  • Treatment typically involves stopping the medication causing the fever.

What you can do

You should seek immediate medical attention. Your symptoms, particularly the persistent fever and new onset headache, are concerning and should be evaluated by a healthcare professional as soon as possible.

What you should look out for

Please seek immediate medical attention if you experience any of the following:

• A severe headache or a headache that is getting progressively worse
• A stiff neck
• Sensitivity to light
• Confusion or difficulty staying awake
• Seizures
• Difficulty breathing
• A rash, especially one that does not fade under pressure
