Kidney infection/problem - uti - treatment

I need advice....please! Mid June i experienced my first known herx! it was very scary and my kidneys went into overload and stopped functioning properly! My bowel also stopped functioning! I was very ill for several days! I immediately came off my new (natural) medication and waited another two weeks before going onto another natural type of treatment (all Byron White based). I am currently battling Lymes and Bartonella (I also have medication for Babesia but have not started on that yet for fear of another overload!!) Over the last 10 days I have experienced extreme fatigue, scary episodes of air hunger, crushing chest pain, and now I seem to have another kidney issue! I noticed a change in the colour of my urine, then a change in odour and last night I began experiencing pain in my lower right lower abdomen (incidentally earlier in the week I was suffering unusual cramping in my upper right area (under rib age/liver area). Is there anyone who can give advice on how to treat this? I suspect an infection as my lymph nodes (noticeably in my neck) are enlarged! I have not been to the Doctors as I have recently just registered with a Lyme Aware doctor who is just very expensive :(. I could go to my local GP but she is not well versed in the complications of Lymes and will ultimately prescribe antibiotics! My body is highly intolerant to 90% of antibiotics hence I have to treat Lymes as holistically as possible while I am able! I have googled natural treatments which led me to discovering D-mannose but does anyone have any ideas, comments, suggestions?

Homeopathy stopped my chronic bladder infections 26 years ago and I haven't had one since, knock on wood! The remedy 'cantharis' is commonly used, but will only work if the symptoms match. I only had to take it a couple of days. If you're not familiar with homeopathy, you might want to find a classically trained homeopath to help choose the remedy that fits your symptoms the best and tell you which potency would be best.

Thank you! I will head out to the health food shops this morning ~ your suggestions are very much appreciated :) x
