I'm almost 4 weeks post OP and have a seroma on my right side that keeps coming back despite following my PS instructions to elevate my legs and refrain from excessive activity. I am no longer within reach of my PS. I left the country to visits family for the holidays and I wont be back in the states for about another month how long can it go without being drained before its too late? I've been draining it myself with some success but an afraid to continue for fear of causing more harm.
