@PUNKEY,
Hi Punk,
Yes, I think this IS the thing. I looked up the condition, and it sounds exactly like what I've had.
I asked him if I could get an MRI. He said no MRI machine in the city (this is a freakin' small Indian town) is likely to detect it. So it may be a while before I get a scan.
He's prescribed a med called Lefax G - it's not available in the US as far as I know, so you won't know about it.
It contains an ingredient called glucosamine which is used for cartilage strengthening. I've had a chat with my dad (he's a doc himself, so I wanted reassurance on the safety of the drug), and he says it should not be a problem.
I'm trying to put together a rehab plan for myself. Will update soon.
