Do I have a blood clot?

Patient: The past three days I’ve had a sharp pain in the inner thigh between my knee and genital region.It feels tense and is accompanied by an occasional bubbling feeling.The pain hasn’t gotten worse or better for the past three days.However, after walking NYC all day yesterday, my ankle is now slightly sore.Would this be a blood clot (I.e. DVT) or a muscle strain?

Symptoms: Soreness and occasional sharp pain in inner thigh.
Slight bubbling sensation.
