Right inner thigh to knee is sore feeling and makes me limp when i walk. theres also a red wide line from inner thigh to knee that hurts when touched?

Emergency!This: Could be a life threatening blood clot.U must go to the ER to get checked.Another possibility is a rapidly advancing infection,which can also be a life threatening situation.Pack an overnight bag and go NOW to the ER.Let us know how u do.

Have that evaluated: This "line" in particular may be what's referred to as lymphangitis, inflammation of the lymph drainage tract that can be related to an infection. Alternatively, it could represent inflammation of a blood vessel related to a blood clot. Again, I would encourage you to be seen sooner rather than later as this could be a sign of something more serious.
