Back pain commonly affects your lower back. It can be a short-term problem, lasting a few days or weeks, or continue for many months or even years. Most people will have some form of back pain at some stage in their lifetime.
Back pain is a common problem that affects most people at some point in their life. It usually feels like an ache, tension or stiffness in your back.
About 8 in 10 people have one or more bouts of low back pain. In most cases, it is not due to a serious disease or serious back problem, and the exact cause of the pain is not clear. This is called nonspecific lower back pain. The usual advice is to keep active, and do normal activities as much as possible. Painkillers can help until the pain eases. In most cases, the pain disappears within six weeks but may come back (recur) from time to time. Chronic (persistent) pain develops in some cases and further treatment may then be needed.

Infectious mononucleosis (IM; also known as mono, glandular fever, Pfeiffer's disease, Filatov's disease, and sometimes colloquially as the kissing disease from its oral transmission) is an infectious, widespread viral disease caused by the Epstein–Barr virus (EBV), one type of herpes virus, against which over 90% of adults are likely to have acquired immunity by the age of 40.
