Jennie_Lou I had a port inserted eight years ago to receive Herceptin infusions. Three years ago a clot was detected under the port via one of my regular heart scans (Herceptin can cause heart problems). My GP prescribed daily Clexane injections, this is a blood thinner and I have had no further problems.( I continue to have infusions every three weeks as I was diagnosed metastatic). Consider speaking with the hospital chaplain or social worker if you have problems locating a support group. Exercise and yoga are both distractions from 'it' and beneficial in so many ways, eg, spending some time with people who are caring for their health and well-being - you may not know or speak with them - but the atmosphere is worth bottling! xxx
