Hello there. lm not sure if this is a symptom of diabetes but thought l should find out. l really should have done this last week as lm now in Angola until the 8th of June. l have noticed , mainly in the morning as l am rowsing awake, l get a feeling running from my lower back, over the buttocks and down the back of the legs until half way down the calf muscles. There is no pain involved, rather it is the opposite, the feeling is rather glorious, arousing even. Stretching of the legs increases the feeling. l should add that l am male, 40.
