Anyone experienced back pain and snowy vision whilst taking Zoloft/Sertraline?
Lower back pain can be a rare side-effect, but given how susceptible people are to back pains this may just be a coincidence. Blurred vision is another rare side-effect, but I've not seen any reports of "snowy" vision. Do you mean you're seeing a lot of 'floaters'? If so, seeing them is a relatively common anxiety effect which the sertraline may be exacerbating if you've just started taking it, or recently increased the dose. Everyone has floaters, but normally they are ignored. Anxiety tends to get some focusing on them.
How much sertraline are you taking and how long have you been at that dose?
