Pain and painkillers. And how many painkillers can you safely take?

So I wanted to ask, how much of painkillers can you safely take. There are two things – one why am I in constant mild pain and two – is it ok to take an over the counter painkiller?

Coming to the first one, I am constantly surprised by the pains in my body. Something hurts all the time. But why!! That’s not normal, is it? Something or the other hurts. And it makes me cranky. It’s not even related parts of my body. Someday it’s the head, someday it’s the stomach and someday it’s the legs.

And the second one, when things hurt I feel like taking a painkiller or having some alcohol. I think I have accepted being an alcoholic as long as I’m not messing up my entire life but painkillers are something I always feel guilty about. It just is so comforting to pop a pill when you’re hurting and then the pain goes away.

I mean I don’t take it often because of the guilt thing but I’m more concerned about myself because of all these random pains. Should I get it checked and if yes, what do I tell the doc? That my body hurts?

My parents have no such inhibitions regarding meds. They take antibiotics like skittles and I’ve always been sceptical of medicine. Probably because I don’t fully understand how it impacts the body.

Anyway, I thought asking random strangers on the internet was a better idea than visiting a specialist so I thought I’d ask here!!
Do you take painkillers and how often?
And is it normal for a 30 something in her prime youth (lol) to feel random pains?
