Talk to General Physician on Can’t Keep Neck Straight While Walking, Gets Turned To Right Side Itself.

My mother is having a severe problem in order to keep her neck straight and stable while she walks, everytime she walks it turns to right then she has to use her hand to turn it back and even occassionally it gets turned when she’s sitting plus facing pain in it as well. We have tried numereous well-known neurosurgeons and Pysicians in Multan and Lahore as Multan is our origin but it’s still the same. Now we are coming to Karachi for the cure. Can anyone please suggest me who’s best to consult for this issue and where? It would be a great favour. Thank you.
