For last 3 days I am suffering from pain while swallowing food or liquid. On first day I can't even swallow normal water and as soon as I took a sip I had a severe pain on right side of chest. There was also pain radiating from right shoulder blade to front in frequent intervals. After taking pain killer , acidity reduction tablet, vitamin D and calcium, now the intensity of pain is lessened but still there is a spasm every two or three hours. At night, I am not able to sleep, due to constant pain at middle of spine on side of right shoulder blade. I have a constant feeling of lump in my upper throat and pain is radiating now to back of spine near back of neck. Kindly advice.
