Oh Bev glad to hear it's your siactic and nothing super major but I know that is painful. I wish i could explain how to relieve the pain through a stretch you can do and it works I know I tried it.
Okay let me see if this works.
sit on a chair with your back straight place one leg on the other (feet flat) leg bent like a man would sit but your back is straight. Now take your bent leg and pull to your opposite shoulder hold for 10 secs. if possible repeat 5 times now do the same thing to the other leg. Do this 3 times a day, and it should stretch it out in a couple of days. Good Luck
