can your legs be rubbed for 2-10 minutes per day? this helps with circulation of a few things not just blood flow. the key is consistency. some oils and creams work better than others.

baclofen was mentioned above in a pump. if you are suffering from tremors that are so small now that you dont know you have them or your pain is covering it up, then maybe ask your dr. to try 5-10mg orally just to see if it works. too much baclofen has severe side affects but is easily resolved by going to a smaller dose or stopping all together.

heat-a warming blanket, thermacares, those things you can microwave for a minute or so(microwaveable wraps?), etc.

deeper and longer massage from a massage therapist. deeper and longer than the 2-10min rub referred above. does not mean deep tissue just what you can handle.

probably a dozen other suggestions could work but try these first.
