Two days back, I had a lump on my right side of neck below jawline like 2 inches down. It got shrunk after a day now it's just 0.2 to 0.4 mm now. And keeps shrinking, now it got hard but it's rubbery. Also from last night I have trouble in my neck like it has swollen although there's no change when I see it. In mirror wall looks fine. I feel it while swallowing. Pain isn't there much I feel like there's swelling. Not much though... Also I been a chain smoker from past 4-5 years. So i was worried. Dear respected sir/mam. It is normal or am i in trouble? Please kindly let me know. Thank you...
