Postpartum muscle soreness anyone?

[LuSmith]

I'm now nearly five weeks PP and since around 2 weeks PP have been experiencing muscle tenderness in my abdomen right from below my ribs all the way to just below my bellybutton. I went to the doctors who prescribed anti-inflammitory tablets a week ago, but in 7 days it's still tender to touch/prod and sore to the skin. I don't know whether this is normal? Pharmacist scared me by saying if tablets dont help in another week I'll have to go back to doctors, now I'm concerned there's something wrong! I know alot of my muscles were stretched throughout pregnancy etc, but has anyone experienced this tenderness and it gone away? It doesn't hurt really unless I touch it or poke it, so its not like cramps or anything..
