Did something nasty to my back on Monday and as it wasn't getting better, went to the doc's today. He's prescribed me some strong anti-inflammatories to be taken only three times a day after food. The first one I took after lunch and it doesn't seem to have done much at all. My question: Do these things have a cumulative effect? ie. as I carry on taking them will they have more of an effect? Supposed to be going to London for the day tomorrow and will be awful if I'm in this much pain!
