Hard To Deal With
Weak Point, Poor At, Not Very Good At, Bad At
noun, な adjective
A "suffering hand" is a little misleading. Think more in terms of the words 苦い (bitter) and 手 (person... remember how that happens sometimes?). Now think of this word like you're bitter about having to work with someone. Why? Because they are extremely hard to deal with.
The reading is that of 苦い (にがい) plus regular old 手 (て). Remember, this is your bitter person, the person who's "hard to deal with." So, it uses the strange にがい reading.
