is the pain for example:

burning,
cramping,
pressure,
trembling?

any nausea?

at what hour of the evening did the fever come, does it come back at all now?

apart from paracetamol, what relieves your pain - eg heat, cold, pressure, position?
what makes it worse?

have you noticed any changes in your mood and emotions since the onset of these symptoms - ask your friends and family if they noticed any change in you too.
