Some chemotherapy treatments can cause skin changes such as soreness and blistering on the palms of the hands and soles of the feet - referred to as hand-foot syndrome. This normally occurs during treatment and can take time to settle once chemotherapy is finished, so it’s possible the blisters you have could be due to this.
The immune system also takes time to recover following chemotherapy which means you still have an increased risk of infection whether this be a chest infection or skin infection, so it’s good to hear that you are being treated with antibiotics.
If the infection and blisters don’t resolve, do report this to your treatment team or GP for further advice.
I have no idea if this is linked to my treatment or not, I've had chemo, lumpectomy and have just started my radiotherapy. I'm also on herceptin, zoladex, ramapril and tamoxafin.
The thing is I now have 4 blisters on one foot and I've never had a blister before in my life. One of them is infected, which I am getting antibiotics for, but I wondered if this was related to my treatment.
