It is annoying how Chemo drugs seem to have different effects each cycle. You just find out how to deal with one lot of effects and then they change! I guess the body does not get back to 'normal' each time so has a few new weaknesses each cycle.
The pins and needles in your fingers and toes is probably a bit of neuropathy. Let your oncologist know about this next visit. I still have slight numbness in some of my toes and tips of the fingers. Makes me more clumsy with things like buttons!
The toe nails sound painful. I was lucky to avoid this side effect. Keep looking after yourself. Deanne xxxx
