After laser argon barrage, seeing floaters and a slight pain even after 2 weeks. Doc said that no detachment and retina is healthy. Anything to worry?

Probably not. The floaters should gradually resolve. You need to avoid doing anything that could increase the pressure in your eye such as heavy lifting, pushing/pulling, coughing, bending your head below the waist, being constipated. Would not recommend taking any medications that may act as blood thinners such as Ibuprofen or aspirin. .
