I notice a small pain around my kidney area and large amount of suds in my urine, is that a sign of kidney problems?

Sudsy urine. Sudsy urine could mean protein is leaking into your urine, especially of it is constant and persistent. Time for a checkup.
Could be proteinuria. Yes, you need to rule out a kidney problem. Advise: go and see your dr. And have urine tested. S/he will advise appropriately.
