Aching joints and muscle problems are common before, during and after the menopause. The joint pain isn’t caused by injury or exhaustion but may be related to fluctuating hormone levels. Collagen is a protein that binds every tissue in the body and when it begins to weaken at the menopause, muscles lose their bulk, strength and coordination and joints become stiff. Muscles become more prone to stiffness after exercise and joints may swell so movement is restricted. If you experience bloating and fluid retention you may also get pins and needles or numbness in your hands.
