Hello!! I am an active 60 year old woman with insulin dependent type 2 diabetes.just this week I am experiencing a very painful left knee, it is stiff, feels tight, difficult to bend and go up and down stairs, pain is constant... I plan to see my doctor in a few weeks , but should I try to see her much sooner? I am using topical voltarin.. not really helping. Leading up to this pain I was helping to lay flagstone outside , on my knees!! I think it is due to that , just wonder what I should take for some pain relief! Thank you so much!!
