Seeking help from doctor / foot specialist/ orthopedic specialist?

I was born with a form of club foot, with my right foot pointed severely outward due to being caught in my mother's breast bone. I am 18 and have been experiencing severe pain for two years. I tore my Achilles tendon on my right side in 2009. I was in a brace for 5 weeks to recover from that injury. I saw an orthopedic specialist who claimed my ankle/foot was not severe enough to perform surgery, but I am in severe pain whenever I stand for more than half an hour, or if I sit for an extended period of time and then put weight on my right leg. Is this due to the birth defect or from the injury in 2009 or a culmination? I take Tylenol for pain but it doesn't work well enough. At times the pain is so severe, like a throbbing ache, that it wakes me up. Any suggestions or opinions of what may be wrong with me?
