I've just been told I have to have further surgery after post-breast cancer implant rupture. Should I carry on running until my op given that it may be a couple of weeks away, or just stop so as not to cause further leakage? Odd question I know but I'd got myself running faster pace for longer after years of being stuck at one slow pace & don't want to wait too long. My last run was a week ago & I have to admit my chest muscles were very sore and my left arm felt a bit restricted (May have just answered my own question!). Any advice on this odd problem?!
