Backache (dor nas costas) - When I have a
backache, I try not to lift heavy objects (or weights, if you wish.)/I try don´t do any heavy liftings or work too hard. I try to maintain myself in a still position. In short, keeping myself quiet. (Quando estou com dor nas costas, eu evito pegar coisas pesadas ou fazer muito esforço.Resumindo, eu procuro ficar quieto.)
Insomnia (Insônia) - When I can sleep*, I read something or just stay in the bed staring at the ceilling.(Quando eu tô com insônia, eu leio algo ou apenas fico na cama olhando para o teto).
When I have insomnia...(you are kinda repeating "when I have...condition X, when I have condition Y, when I have condition Z...")
Hope it helps!
Sorry for having being so late! I had some rough patches these days...! road of life got bumpy, bumpier, and bumpier still...
