It seems to be due to the osteoarthritis and is common issue of advancing age. Degenerative bones disorders cause pain on weight bearing joints and once we kick start the pain relieves to some extent. You can take an over the counter painkiller. We have to check for the Serum uric acid and Calcium levels too. Restrict on the protein diet and if you have to take seafood is good option for you. Consult an Orthopedist for evaluation of the joint. He will rule out the reason for the bruises on the leg and also will see if there is inflammation of the joint and for that he may go for the inflammatory fluid drainage and may inject Corticosteroid + anesthetic injection into the joint space for fast symptomatic relief.
