I Have Constant Visible Pulsing In My Calves And Ankles.

I have constant visible pulsing in my calves and ankles. Worse in left leg. Some tingling. Lumbar MRI shows aging deterioration, no pinched nerves. Have had this mildly for 12 years with periods of relief. But after some PT doing some Pilates moves 3 weeks ago, this tingling and pulsing has been non stop. Also have terrible cramping or spasms in trapezius muscle. Neurolgist suggested Cymbalta, think peripheral neuropathy . Have only been taking for 6 days but no help only making me more anxious til my body gets use to it I guess.
