When I was evaluating different methods of treatment, I was told by the PD co-ordinator that I could go swimming in the sea, (have done this numerous times,) but to avoid public swimming pools and NEVER go swimming in the river.The advice was to clean the exit site and apply a new dressing on exiting the water. No need for waterproof dressings etc.It seems that different countries may have varying protocols regarding swimming. (Maybe we're a bit more relaxed about it all in Oz?)
