Hello Doctor
Hi, as you mentioned your symptoms, your work style and your age, I could sense something here is the stress. You have stress of work all the time may be, then since you may be working on a computer for a long time your spinal muscles must have gone weaker, also your metabolism must have slowed down. What I can advise you to do regular physical exercise, breathing exercise and meditation. This all three when applied together will assist to remove your weakness and tiredness. If you have further query can contact meRegardsJay In Chat Doctor.
