Fibrositis is an expert medical expression for stiffness and pain deep in the muscles. It can be caused by a number of factors, from the physical load of the muscles or joints to the emotional tension that is reflected in muscle tension. If you have fibrositis attacks, do not worry – there is basically nothing wrong your muscles – but you will still feel sharp localized pains, and there may be slight swelling in the area of the affected muscles.
Fibrositis often affects the backs, causing unspecific pain. This is a common illness, especially in people who have undergone middle age, and usually disappear after three to four days.
Soft baths (for relaxation) and analgesics (paracetamol) should relieve the pain. If the pain persists for more than a few days, contact a doctor who will prescribe you a stronger muscle relaxant remedy, but only if he is certain that your symptoms are not symptoms of some more serious illness, such as rheumatoid arthritis.
