Hi.. work from home has caused this complain among many. Make sure that the top of your laptop screen is in the same height of your eye level. Use an ergonomic keyboard. make sure your elbows are rested on an arm rest of the chair and both the arm rest and table height should be same. You may use a Bluetooth keyboard or portable keyboard and keep it close to you also the mouse, so that you don't need to stoop forwards towards the table.
Next Steps
For the ongoing pain I would recommend ice pack. you need to take one on one consultation to address the ongoing symptoms.
Health Tips
Follow proper ergonomics and keep your self active. Drink enough water. and do frequent deep breathing to de stress.
