Hi Rohan,
I've now had 3 arthroscopies and recovery time for each has really varied. It's really good to go off and exercise, but ALWAYS check with the physio first!!
I also had trouble with clicking after my third op, and queried this with the OS. Verdict was a tendon snapping over the joint, and this is a common phenomena! Everything has settled down for me now and I'm sure it will for you, too.
Ultimately, listen to your body. It's bound to hurt on and off for the first 6 months, but anything 'really' worrying should be investigated asap. Good luck and happy new year.
