Burning sensation while peeing

Not sure whats going on but it seems i have to pee every ten min and there is a slight burning sensation in the head only. Its like nothing comes out for 3 seconds and then i just pee for about 3 seconds only.
Ive never done a cleanse except i do drink cranberry, kelp, and take multis.
I also take xenadrine and levorex which is a fat burner with carnitine, green tea, grapesead,vinpocetine,,bioperine, and evodiamine, . I take this mon-friday and figure i needed to clean myself out and maybe its because of this.

I took some alfalfa tablets awhile ago and it seems better now but still there. Tweet
