I'm having some pain in my lower left leg that's seemingly random. It's sore, but occasionally ramps up to feeling like I'm about to have a charley horse. I haven't injured it (that I know of). I am a former smoker (quite 5+ years ago) and overweight, and my family has a history of strokes and clotting (my dad just threw a clot back in December). I don't know how to differentiate between a little tendonitis in my Achilles Tendon and the chance that I may have a clot causing me some pain, or how urgent it may be (the pain isn't terrible, just occasionally annoying because I limp).

Do I have time to wait to get an appointment with my doctor's office, or should I go to an Urgent Care?
