I started to get tingling /PN symptoms around week 8 of taxcel - not as bad as what you’re describing. I had preexisting fasciitis (mild) with one foot which flared up daily once on taxcel. Hands affected as well. My oncologist was concerned and after discussion with me , she reduced dosage to 75% strength , with aim to get me to week 11 at least. She said she’d discontinue it if it did not result in lesser symptoms. Luckily that worked for me - symptoms reduced , so I about to have final,dose week 12 on 1st December. Had your oncologist discussed that with you as a option? We all know the taxcel is a important treatment option for us , but PN symptoms will not resolve completely if they get severe so there’s a balancing act between benefits of taxcel,and damage to nerves.
My nails on feet all gone , and some on hands have also been affected ( splitting ‘ falling off). I wish I had tried dark nail polish on them before I’d started chemo ( round 1 was AC, taxcel round 2). The nails were sore on round 1, and then discoloured and started to,split later in round 1 . I didn’t try cold treatment
