<s>[INST] Hi, I am 42 year old female, I have been experiencing pain from the back of the neck unto the shoulder blade. I thought I probably just slept in wrong position or pulled a muscle and that was the result, its now day 3 and the pain is still there. My husband noticed there is a small pea sized lump on my left shoulder, when he presses on it the pain seems to be less for that time. Wondering if that is something minor like me pulling a muscle? [/INST] Dear patient, your symptoms are acute i.e. of 3 days duration, severe, and if the pain gets relieved in one position and increases in other, then the chances of its being muscular is more. It could be trapezius spasm, also be clear that you do not have any radiation of pain into your arm and hand, if It's so than chances of neural origin is more. 1 Take rest in position, which relieves the pain,2 take analgesics like ibuprofen with muscle relaxant medication,3 Apply infrared heat from lamp, or heat from water bottle, and see if pain soothes.4 Local analgesic spray can be used for faster effect. I hope that answers your question. Thanks </s>
