What is best antibiotic for treatment of uti?

Depends. Selecting the most effective antibiotics depends upon the organism(bacterium) isolated from properly collected urine sample. Given the multiplicity of causative organism in urinary tract infections and antibiotic resistance bacteria develop, there is no panacea.
Cipro (ciprofloxacin) and Bactrim. Best antibiotic depends upon the causative organism (bacteria). Most utis are due to e. Coli and most utis will respond to a short course of cipro, (ciprofloxacin) bactrim, or macrodantin. The latter sterilizes the urine ANS is great for lower urinary tract infections ie cystitis, but not good where good tissues are require as for pyelonephritis(kidney infection) i deally urine should be cultured before treatment.

Can recurrent uti/ antibiotic use cause ic? Is it normal to have slight pain/sensitivity during urination after treatment?

IC is not repeat UTI. Lower uti's are usually responsive to antibiotics, but recurrences are common. Other conditions besides infection can cause frequency and urinary discomfort; interstitial cystitis is only one of many. The hallmark of ic is visualization of 'glomerulation' on cystoscopy; however, ic may exists without seeing this. Potassium sensitivity test in the office can confirm. You do need a diagnosis.

Frequent UTI. After amox treatment 1000-9000 cfu/ml of gram positive cocci isolated. Md did not prescribe any antibiotic afterwards. Should redo test?

If yes, have you felt better in voiding in 1-3 days after taking Amox? And in general, a colony count of < 100,000 cfu/ml is considered not clinically significant. More?
