Head hurts more when i lay my my down, sleep at night with an ice pack on my head. could i have just pulled a muscle in my neck or should i be more concerned? thank you [/INST] Hi, thanks for writing to Chat Doctor you seem to have pulled your trapezius (neck muscle).please do the following;1.support your neck with soft cervical collar.2.take rest, avoid Chat Doctor. 3.start doing hot fomentation by using a hot water bag or electric heating pad. Do it 3-4 times a day.4.take anti-inflammatory like ibuprofen or acetaaminophen.it should be fine in 4-5 days. Hope I have answered your query. Thank you </s>
