Consulta sobre dolor de espalda...

Since around mid December last year I've been experiencing back pain. It started off very minor, it would just ache a little when I layed down after lifting things such as shopping bags etc. However, at the end of November I had a fall and fell down a flight of stairs; ever since then my back pain has got extremely worse whenever I lie down in bed on my back. It sends a sharp aching pain through my back, and is mainly centred at the bottom. 

I am just curious as to whether it is anything serious and I should get it checked out, or whether after time it'll get better. 

Thank you for any help you can give  

Just to add - it started in December in 2014 and I had the fall November of this year confused

Hola Laurajayne, algunos dolores de espalda pueden mejorar con el tiempo si descansas, sin embargo, una caída es más grave, pero por favor no te asustes cuando te aconseje que vayas a ver a un médico, quien probablemente te enviará a una exploración para determinar un tratamiento que te devuelva la salud y el bienestar. Todo lo mejor, Laurajayne.

Hi I agree with Frank.  You may have damaged something in the fall and need to get it checked out.  Meanwhile always try and liff things using your knees to help take some of strain off your back.  Never twist and turn at the same time when bending over either as this will make it worse.  Let us know how you get on please.  x
