I sustained a whiplash injury in a road accident in 2005-06. However, the injury came to light 2 years later when I developed pain and stiffness at the back of my neck and left shoulder. The pain and stiffness used to be worse in the mornings but gradually subsided after taking a bath and further during the day. What got me worried was a restrained movement in my left arm when I had slight difficulty in lifting it beyond a certain point over my shoulder. I consulted a physiotherapist who recommended MRI after seeing my X-ray reports and a whiplash was revealed. The treatment began and I recuperated in a matter of 2-3 weeks. I was given a set of stretching exercises by my Physiotherapist who asked me to do them regularly everyday and never stop. However, I didn t follow her advise as it seemed alright. I love fitness so I do some exercises atleast 2-3 times a week viz. pushups and crunches. A week back I think I overstrained while doing crunches though I am not sure. But the next morning I woke up, I had the same pain and stiffness at the back of my neck. Please let me know is it because of the cruches or is it because I stopped doing the exercises recommended by the Physiotherapist? Last night I also took a mobizox which relieved me a lot. Please advise.
