Hi Welcome to HCM. As per your description it seems that your neck pain is not due to spine problems but its due to muscle spasm .It is not a serious issue which can be treated easily. I would like to advice to take tab . Combiflam or tab. Diclofenec twice a day for 3 days . Also apply local ointments such as volini or volitra etc. If it does not subside then add tab myospas . still if you have any doubts pl feel free to ask. Don t worry. You will be fine soon. Take care.
