What do you mean by rolling your leg? If you can walk without issue on your heels and or toes then your issue could be positional. I have all of the arthritis issues myself (I am only 33) and while I have never gotten dizzy as you're experiencing, I have lost strength of certain muscles when I ended up in certain positions. Yoga all but cured my issues. I know how bad chronic pain can make you want to simply exist and take it easy which is the worst thing that we can do. Are you spending a lot of time sitting or laying down with little exercise? If you are, I would suggest that you do some yoga and get some walking in as you are able. I am no doctor but from my own experience, when I began doing yoga and walking, a lot of my issues that are very similar to yours were greatly reduced and I got a ton of mobility back that I lost in my accident. I no longer needed anything more than Ibuprofen.
