hamstrings

I'm a little stuck... Click here to teach me more about this clue!

'thigh muscles' is the definition.
'hamstrings' can be an answer for 'muscles' (hamstring is a kind of muscle). I am not sure about the 'thigh' bit.

'nasty stings harm' is the wordplay.
'nasty' indicates anagramming the letters (a nasty or wrong spelling).
'stings'+'harm'='stingsharm'
'stingsharm' with letters rearranged gives 'HAMSTRINGS'.

Can you help me to learn more?

(Other definitions for hamstrings that I've seen before include "slows down" , "Tendons" .)
