Health's going, suffering in disputed ME territory (5,7)
I believe the answer is:
golan heights
'disputed me territory' is the definition.
(disputed Middle Eastern region)
'health's going suffering' is the wordplay.
'suffering' indicates an anagram.
'healths'+'going'='healthsgoing'
'healthsgoing' is an anagram of 'GOLAN HEIGHTS'.
'in' is the link.
(Other definitions for golan heights that I've seen before include "range of hills" , "disputed territory" .)
