Hi - I've Bee Having Aches / Pains I My

Hi - I've bee having aches / pains I my right leg - on and off for few months but more noticeable last couple of weeks. Hard to describe as pain moves around sometimes fees in bones sometimes definitely muscular - mainly but not confined to lower leg. No major impediment to walking though faster pace causes twinges. Hard to say for sure but would I be better seeing GP - possible scan or getting physio / osteo
