Thanks for posting your query.
With the available described symptoms, there appears to be possibility of engorged neck veins/ palpable carotid arteries.
Gluconorm PG L1 contains glimipride, metformin
and it is never associated with palpable bulging mass in neck.
You should consult with internal medicine specialist/ cardiologist and should go for through check up.
You should go for complete blood count
, chest x ray, electrocardiography
, renal function test and serum electrolytes.
You should also for colour doppler of both side common carotid arteries.
Meanwhile you should take low dose diuretics if you are feeling difficulty in respiration.
