Your symptoms may be related to stress, anxiety episodes, muscle strain/postural issues from prolonged computer work, lack of sleep, fatigue,
vitamin deficiencies, or other medical causes. The feeling of internal heat, restlessness, weakness, headaches, and back pain can sometimes occur with anxiety or prolonged stress, but a proper evaluation is needed to rule out physical causes as well.
Next Steps
Try to maintain regular sleep, hydration, meals, exercise/stretching, and reduce continuous screen time. Take frequent breaks while working on the computer.
It would be advisable to consult a physician for examination and basic investigations such as CBC,
thyroid profile,
vitamin B12,
vitamin D, blood
sugar, and BP check if symptoms are frequent.
Health Tips
Seek urgent medical care if you develop chest pain, severe breathlessness, fainting, high fever, weakness of limbs, severe headache, or worsening symptoms.
