I am suffering from cervical pain in the left shoulder and currently taking the physiotherapy treatment which has really helped me a lot but from pay 4 days I am having heaviness in my center to forehead which seems to get started from my neck. The intensity of the heaviness starts from the mornings itself and get increased by the evening. So when I consulted my physiotherapists he said it might be due to BP some I have that and take medication but it was all normal. therefore I would like to request that what is the cause of this and in which specialty I should consult since due to this I am not able to concentrate on my work at all.
