Hi Natalie

Yes Zantac aka Ranitidine is available OTC. Small packs are available at supermarkets. It is amazing what you can buy at supermarkets now. I do reccomend that Kate speaks to her Dr or pharmacist to decide if Zantac is the most appropriate treatment for her.

On the pelvic pain - sit down to put on shoes, get dressed, don't put too much weight on one leg. Avoid leg lifts and anything that hurts

Hope you are feeling better today
