I am a housekeeper. Im always moving, bending, twisting , lifting and ect. and keep in mind ive never had back problems in my life. Three days ago i noticed at the end of my shift my lower back had a dull aching pain. throughout the next few days it has not improved at all. with medicine or icing it and resting after work. . its day three with burning , numbness, stabbing pain in lower back. should i take time off work for recovering ? just a few days.. since the lower back pain started i have not had a day off (3 days ago).
