I'm back! Well, had the misfortune to have to see the physio the other day since I appear to have got myself a pinched / trapped nerve in my neck! Major pain down the trapezius / delt area and neck! Apparently I've a very stiff neck msucle, but I reckon it was cause by doing heavy shrugs in the gym, with bad form.... and a delayed effect. Anyway, apart from that, I asked her opinion on my knee situation which I was going to do within the next month anyway! Basically, she thinks my knee isn't tracking correctly at all and my right leg overpronates somewhat. VMO is very weak and should have had rehab to get that sorted - only a year too late hey?! It's what I've been looking at recently, so going back again tomorrow for both neck & knee assessment and hope to gain something at least! Thanks for all the replies so far, more information in any form is worth it, I can apply your thoughts and see what fits! Any further advice is very welcome!
