Hip pain... Could it be from my knee injury...?

[Dea B]

I have an injury to my left knee(long story) and I am in am immobolizer(have been for the last 5 weeks) and was told 2 weeks ago(when i went to the specialist) that i could begin WBAT(had previously been NWB followed by minimal to limited weight bearing) and the specialist said that if i was comfortable with full weightbearing that it was ok to start but for long distances or if im gonna be on my knee for a length of time to use at least 1 crutch so that i dont limp as badly and get pains in my back... so last week i finally felt as though my knee wasnt going to give even with the brace on(still NWB with it off cause of instability) so i started going for the most part without the crutches(i still keep them in my car just in case)... well Friday and Saturday i did alot of walking and my knee was killing me afterwards, so today i took it easy and kept my knee elevated most of the day... but now my right hip is really sore, but the thing is that it only hurts when i sit with my leg bent
like if im sitting indian style... and then when i straighten out my leg, also if i lay on my right side i get an ache in my right hip... Is this from putting alot of stress on my right leg?

and should i go back to using the crutches(my knee has been hurting more since saturday)?


also today when i was getting off the couch something in my knee(left) popped and i got this weird pain, and loose feeling in my knee, what do u think i did if anything at all?


thanks
I go back to the doc on Monday 4/28...

and when i did alot of walking on Fri i was using one crutch and my knee was still hurting... and Saturday i didnt use the crutches but i didnt think that i would wind up doing as much walking as i did(stupid i know) since i was at a cheer competition(our last one... Nationals... i was there to cheer them on)
