Hi there. Welcome to my Virtual Clinic. I have carefully gone through your case and in my expert opinion its stiffness of neck because of muscle spasm. Don t worry about it. We can treat it well in a timely manner. Keep your pillow adjusted when u sleep. When u need your head end up, don t take one extra pillow to do it. It will make your neck uneven with the rest of spine and hurt u in the morning and day long. Muscles work whole night to adjust and handle the disbalance in spine level. Rather u should lift the head end of bedside up as needed. But ur pillow should be of a comfortable thickness. Use softest available pillow. Keep urself away from tensions. Preoccupied mind and tensions can cause neck stiffness and pain. Remedy:- Now if you were a patient at my clinic, I would prefer to prescribe you proper rest; Tablet Orphenadrine citrate(Norflex) twice daily for only 5 days. Tablet Ibuprofen 600mg(Motrin) twice daily for 5days. And apply Voltaren Gel at the affected area 3 times a day. Head padding the area also soothens a lot. I wish u the best of health. Stay blessed and have a good time. Dont forget to give me a feedback if found Helpful. Regards: Dr. Hanif Philadelphia USA
