What could be causing a cough and upper back pain?

I had a pretty bad cold for a couple weeks. The other symptoms cleared up, but the cough is getting worse instead of better. I’ve also started getting sharp pains around my upper back, especially when I start coughing, and usually on the right side.

My sister is a nursing student. She said she heard crackling in one lung and some wheezing in the other.

Any ideas on what it could be?

what are the best hair care / skin care products – lotions shampoos etc?

I'm planning to get my girlfriend some hair care / skin care products for her birthday. I don't want just average stuff, I want the BEST — the stuff that will make her feel like her hair is healthy and shiny etc. And the lotion that is good for her skin and all that.

Is there a certain brand that's excellent? it's ok if I have to order it, her Bday is a couple weeks away still.

Thanks
