Can l suggest calling NHS direct for further signposting as your hospital does not offer 24/7 helpline. Your right if it was just a dry skin reaction Ìt would not be on the soles of your feet. I have only had that happen with one drug and it was not fun as it was everywhere.
I recommend making an appointment via their medical secretary to see your oncologist. Some of us do have allergies to some chemotheraphy drugs and your oncologist will know how best to manage such. In my case it needed a change from ducataxel to nab paxitaxel as l kept having adverse reactions to the ducataxel drug carrier. The delayed skin reaction that causes my skin to dry out and excema to flare is managed by a course of predisalone and daily antihistimines with extra prescribed emoillents. It all helps.
Tips that have helped me: keep more hydrated than the recommended 2litres per day. It will help to keep your skin hydrated during chemo.
Use pure cotton bedlinen that can be washed at 60c. Use a liguid none biological detergent and not a biological. If you need to soak in bio do so then use the towel/ hotter sheet wash option with none biological after. None biological liguids leave less irritating residue beside than powders.
Wear cotton next to your skin. If cotton is not right you can try silk unde layers but they cost far more. I buy seam free knickers without latex and cotton covered latex free elasticine from Eczema Clothing. Not cheap not fancy but so glad l did. Avoid wearing synthetic fabrics next to dried out skin as they can irritate. They trap any sweat and dry skin flakes which set off irritations.
Watch out for any lost hair sticking to your skin after a shower, Ìt acts like itching powder. Shower Ìt off with extra cool rinses.
Avoid using soap- try Sanex Zero as an alternative. If you react to that speak with your oncologist about prescription soap substitutes. Avoid perfumed and surfate containing soaps etc.
Try using cooler water to wash with as hot water can further dry out dry skin. Always use an emollient after.
Moisturise your whole body daily. Always moisturise after washing or doing housework
I recommend wearing gloves for house work. ASDA stocks nitrile washing up gloves in larger stores. If like me you love gardening make sure you have good garden gloves. Watch out for latex as very dry skin can develop a sensitivity to that too. Many plants and weeds can set off skin reactions if you have sensitive skin. Consider wearing sleeves to protect skin on your arms from brushing against foliage.
If your skin is being very reactive please let hospital staff know. They will try to use sensitive skin tapes etc for blood tests and chemo. Let them know if anything does begin to irritate before it can get really going.
Before using a suitable sun bloc use your emoillent 30 mins before applying, allow it time to soak in so you have a thin layer between your skin and the sun bloc. Larger boots stock some of the (more expensive) reactive skin sun bloc ranges. Look for none perfumed and high plus factor.
Be a tad cautious with synthetic wigs in the heat, have a back up plan in the form of cotton scarfs and pure cotton lined chemotheraphy sun hats. I tried silk scarves but alas they do need some hair to grip on to.
Hope that helps a little and gives you some ideas.
