There are a few things that are significant in your history: Being overweight and stiffness of the extremities
which seem to be worse especially in the mornings.
One main differential here is osteoarthritis. Being overweight puts you at a higher risk of developing
osteoarthritis. "In the United States, osteoarthritis (OA) is the most common form of arthritis affecting
about 16 million Americans. Obesity is a well established risk factor for osteoarthritis of the knee, and
possibly the hip. More than 70 percent of women and 35 percent of men with OA of the knee are overweight. It
is characterized by pain at the knee on beginning motion, such as arising from a chair, and increased pain
with prolonged use. In the early stages of OA, the pain is relieved by rest, but as the disease progresses,
the pain can persist after activity, and even interfere with sleep."
I would suggest an initial consult with your physician for a complete assessment of the joints and the
extremities. It should be necessary to note that weakness is not mistaken for stiffness here and that the
joints are involved and not the muscles. Blood tests for blood sugar and cholesterol levels may be obtained to
rule out diabetes and cholesterol elevation. It is necessary to engage in regular exercise regimens which are
low impact exercises (eg swimming , brisk walking). Choosing the right forms of exercises is important. Using
the right rubber shoes with good support is also essential.
