Eye Floaters. Could be somthing serious?

I am suddenly experiencing a lot of eye floaters in one eye. Actually,i had taken a medication for something two weeks ago which had caused me some gastric and acidity problem. During that time,one of my eye had suddenly started to pain and vision became bit blur. But then i took a gastric medicine and along side it,i went to an eye doctor who examined my eye and just gave me simple allergic medicine which reduced the redness in eye and on visiting him again as he told after 3 days,he said there is no problem anymore (i had little floaters but he said its not problem).Then my eye had again recovered 99% recovered 2 days ago until again i got acidity problem and when i woke up,now again my vision was blurred. Now,in the 2 days.without medication,the acidity is ofcourse alr gone and i can see almost fully again but i am seeing a lot of floaters in my eyes. Is it a normal thing that will go on its own or is it something serious.I am just scared coz google says it could be somthing serious
