tight right leg

I woke up in the night and my right leg was so tight, it was really uncomfortable, I tried massaging it loose with my deep tissue massager, but it didnt help. I had a wee and it released a lot enough so thatU could go back to be. Now its improved a lot. The tightness was quite unbearable, but hey I survived. I ann going to see a physio today, who knows about the neuro side of things and about nerves and also practices acupuncture, so the meeting will be interesting and hopefully advantageous.
