Joint pain on my upper side of thigh.

Actually, every year i go to Shree mata vaishnodevi for the last 3-4 years but this time in November and December i feel light if i will be able to go or not bcoz i am always going by walk not by paalki and horse so it's approximately 22kms and i go there in january but this time it was too much tough for me.. Between half way i feel that is enough i will not be able to do this time but my friends push me and we reached and came.. But one pain started there in my upper thigh joint in Shree Mata Vaishnodevi, so I thought this is normal muscle pain but that pain is not gone yet it's starts anytime when i walk 100mtr only.. And because of that i feel difficulty in walking, folding my leg and usually it starts in night. Please suggest what i need to do.. I'm too afraid.
