take a warm bath and do some light stretching (and i repeat light because you ca over stretch when your muscles are as relaxed as they are after a bath, and you could do more damage) after tha bath. massage all the major and minor letg muscles, @(cross laterally, ie. at 90 degrees to the direction in which the muscle runs, for the quads this is left to right of the thigh, at alternating places.) do the ,massage whilst in the bath. and don't run after the bath.
also advisable is some cross training, try cycling, and put moderate effort into it to begin, don';t over do it, but work up to as high an intensity as you can. no specialist bike needed, a regular mountain bike will suffice no suspension required until you go off road.
and have fun, don't slavishly seek for constant improvement, this may well lead to burnout, but don't go toooo easy all the same.
good luck with becoming a full scale runner. i admire your eforts, don't give up, ever, you will want to in a few weeks, but think of the benefits you will reap through your perserverance.
have fun,
phil
