Update on this, Well paid for 2 physio sessions, old age,desk job and bike riding caused the nerve problems,well worth the expense did not realise how inflexible i was around shoulders and neck. Enjoy the stretching so much that i have incorporated more overall body stretches, i would recommend trying to get stretches into your fitness routine.purchased a foam roller and this has helped to recreate the massage .Not complete cure but its enabled me to get back on bike.
It has taken a month off bike but that included a viral infection that probably accounted for 2 weeks.
This weekend completed pain free 16 miler on road bike, and yes stretched afterwards.
Yet to get bike fit saving up for that one.
