Lower back left LEG pain?

Very severe, constant, gnawing lower left leg pain.?

• I haven't been doing anything strenuous. I exercise, run, walk, etc on a regular basis. Yesterday, I spent a few hours walking through my town, but this is something I do almost every day and has never caused discomfort, fatigue, and certainly not pain. I haven't done much of anything today, relaxed, did some fine tuning to the lawn with the weed-whacker, and have been browsing the internet since. This is also ritualistic for me, I have days like these quite often. I noticed discomfort in my left leg and shrugged it off as poor circulation and adjusted my seating. The pain has grown worse over the course of about thirty minutes and is now a very deep, gnawing pain. I consider myself very tolerant of pain, but I find myself breathing hard now and the pain is overwhelming, I can hardly focus on typing, let alone any actual involved activities. I am very familiar with pulled muscles, shin splints, etc, but this is certainly not that. I have no swelling, heat, bite marks, or any other tell-tale symptoms of more common leg injures or disorders, diseases, etc. I took two Aleve about ten minutes ago and the pain has yet to subside, only worsen. Should I see a doctor if it persists? How long does this have to continue before I contact a professional? I can not drive or do anything of the ordinary in this state. If this is familiar to anybody, please let me know. If it will pass, I would love to just hear that as reassurance. Thank you in advanced.
