Started getting strange headaches.. Please help

Some background info:

I'm a 21 year old male, in good health apart from suffering from a anxiety and IBS for a while. I have been on 20mg citalopram for about a month now. 

So the past four or so days I've been getting headaches every day. They are quite random in nature and are always very mild pain wise, just mostly an annoyance. Sometimes they will last a while and will travel round my head, other times it will literally be a pain somewhere in my head for like a second. They seem to trigger from poor lighting and a bright TV or bright lights etc. I'm having to squint a lot because of this. I had an eye exam last week and my eyes are fine apparently. Paracetamol seems to get rid of them and eating food seems to as well sometimes? But then they may randomly come back later. 

I was wondering whether they are a side effect of the citalopram as I never really got headaches before these four or so days (obviously the odd one here and there, but nothing like this) 

Obviously as an anxiety sufferer these are quite worrying for me, so what do you guys think? Some reassurance would be amazing for me. 

Thanks in advance. 

Bless you I'm the same know exactly how u feel wana talk?

Hi jack, having anxiety makes things worse (trust me I've been their) so try not to focus on it too much. Poor lighting (in some supermarkets I get migraines due to the lighting) it does say side effects of the medicine that are very common are headaches so it might just be that. Try not to worry smile

Thanks for that reassuring reply. It means  a lot. So you think I shouldn't worry and it's nothing serious? II've suffered from anxiety for a while but never really got headaches from it. Mostly just chest and stomach issues.

I'm gonna try ween off the citalopram and see if that helps. 

Thanks again smile 

What do you think then?
