Pain in my inner upper thigh

laterdude,
Sounds like you probably injured one or more of your adductor muscles. They're a large group of muscles that bring the leg towards the center or across the body; located on the medial (inner) thigh. They stretch from the pelvis to the tibia. (Soccer style kickers use these muscles a lot.) A strain of the adductors can cause pain at the site of injury, possibly radiating into the groin and down to the knee. Local swelling can sometimes cause small sensory nerves to be compressed and producing tingling. The pain associated with a muscle injury is worst when the muscle is used; in the case of the adductors - as when moving an object across in front of your body with your foot.
It can sometimes take a while for symptoms from a significant muscle tear to resolve. You can try some ice (acute pain/swelling), heat (more soothing), hot tub/whirlpool, massage, compression wrap (not too tight), and/or OTC medicines such as tylenol or motrin (if not countraindicated by any health problems you may have). If the symptoms persist or get worse (increased swelling, increased pain, need for cane/crutches, etc), then you should probably see your physician. Hope you get back to activity soon. Try not to kick anything so much larger than yourself in the future. Your car doesn't feel the pain. Good luck.
