Well with Dbol's there is a tendency for the legs to feel tighter, or sometimes fatigued due to the water gain. Also with a shock to the system with gaining that much weight in a short time will effect that also.
There are many factors in this situation. But after the water gain, has finally diminished (if you even gained that much water) You should feel alot better. I know when I put on bloat I get some feelings like your describing. But it all differ's
There are many things to take in effect here.
