Hello my friend.
Well, since from last one year you're living with this issue and visited multiple healthcare providers, so by now you must be knowing that wrong sitting postures, and more so, the environment that you're working in, may be the major causative factors.
You guys usually work in the temperature which is supposed to be healthy for your computers(20'C to 26'C), but unfortunately it's not as healthy for humans(37'C). So, this huge temperature difference could be one of the reasons for your suffering.
However, Considering the weight and height that you have provided, your BMI shows normal values and suggestive of a better physique. So, may I ask you to practice some Yogasana.
* 'Surya Namaskar' - It is a very popular complete body stretching exercises. Always underrated, but has a potential to do any magic.
* 'Ushtrasan,Bhujangasan and Halasan'- stretches the neck, shoulders and spine, improves blood supply and thus hepls to relieve pain.
* Temperature therapy is also very useful. One can simply use hot water bag or electric heating pad.
Caution- Avoid excess heating.
* Avoid sour food like curd, pickle etc.
But still I would advise you to consult with your healthcare provider before you start any treatment.
Get well soon...!
