Another Day, Another Disaster...

I know I've spoken (or written) about being left-handed breaking that hand and subsequently relying more and more on my right hand for almost all fine motor skills.  Well, my trusty right hand has been increasingly weak (or  it has seemed to me)and as I was running bathwater last night, I realized my right hand wasn't registering hot/cold.  I checked it again later, waiting until my fingers were positively pruney, same result, no feeling at all where temperature is concerned.  Today I have simply dropped lots of items, repeatedly, so I'm performing the same "field tests" on my hands as yesterday, and it's heat my right hand isn't feeling, my spouse suggested it might be a delayed reaction to Temodar, which I reacted badly to anyway.  I am fairly  freaked out the loss of my one, good hand would have a huge impact on my daily circumstances.  So, if anyone reading out there have any bright ideas or heard of this condition in general, please indicate!   One bike ride/60 min/level 2 - 2 walks
