Suggest Cure For Pulled Muscles In Left Calf

I'm 31 yrs old , 4'10 and about 150 lb . For about a month I've had what feels like a pulled muscle in my left calf . No swelling or bruising . Been using aleve and icy hot but doesn't seem to help. I do work 10 Hr shifts on my feet , which could be slowing down the healing process . Should I continue self treatment or be seen ?
