Hi Sir,
It seems that you are doing sitting job or use mobile and laptop for many hours. Also you are overweight. First manage these things and if somebody told you that there are misalignment issues then get proper treatment.
Next Steps
You can also consult any other physio or ortho and have there reviews, but not online.
