test prop question about ankles when running *karma

[danymal04]

When I'm on test prop, I discovered that my achilies and ankles hurt when i jog/spring/run... is this because of the extra weight that I am carrying when I'm trying to jog/sprint or the BDprop. Because I think it must be the extra water retention and weight or the pumps because whenever I'm cycled off, they seem to go away.

Any info would help... thanks
