If i hurt my back moving furniture, what is the best way to reduce the discomfort?

REST: ICE and after 4 hours HEAT applied to the back along with anti-inflammatory medication eg: IBUPROFEN should bring relief for a simple STRAIN/SPRAIN in 24-48 hours. If you are unfortunate enough (as many are at age 65) to have underlying arthritis or a PRIOR HISTORY of back pain this will last longer AND you should NOT be moving heavy furniture! Hope this is helpful Dr Z
