welcome to healthcaremagic
first of all i would like to say tht , mountoux is for infection not particular for t.b
i agree wid dr tauseef, ur symptoms seems to be an arthritis
, better u go to consult a orthpaedician and confirm hw much spaces reduced...
and i want to suggest u tht u do some hams stretch (u hv to put ur heel of the affected leg on the table of ur navel level height and thn try to touch ur big toe by opposite hand , and if u r able to touch thn hold for 30 sec), definitely ur pain will cum down.
otherwise u can go to a physio clinic.
