No **** your not lol. Imma quote this guy,who pretty much nails it.
"DOMS is decreased through the prevention of swelling (cold shower or ice) and then increased circulation (hot shower or heating pad) which allows the muscle to heal faster. You **must** START with cold to help reduce swelling in the muscles, but it really doesn't matter if you end with cold or hot. Ending with cold usually feels better if you're stepping out into a steamy room. Starting with hot will promote blood flow to the muscles which will increase the rate of swelling initially which will prolong the healing process. Hence, why we ALWAYS ice after say a twisted ankle. Shower intervals should be done a few minutes at a time.
Flushing of lactic acid has nothing at all to do with DOMS, and contrast baths/showers will NOT flush it. Lactic acid is a metabolite, per recent research if you've been keeping up, and not a metabolic waste product produced by muscles. When it is converted back into pyruvate and sent through the citric acid cycle it helps to rephosphorylate ADP into ATP per oxidative phosphorylation. Contrast showers or baths will do NOTHING to help speed up this process; this is all based up the cells capacity to process metabolites."
