Yes, Please. I Continue To Have What Appears To Be

Yes, please. I continue to have what appears to be very small blisters show up on the tips and sides of my fingers which then erupt. The skin cracks and hardens somewhat. I also have the corners of my mouth crack open as well at the inside tips of each nostril. I suspect it might be an issue with an overgrowth of yeast, but could it be something else that I should consider? I have asthma, interstitial cystitis, IBS and sacral/pudendal nerve damage. I take 7 - 8 medications to treat these various medical issues. Any guidance would be greatly appreciated.
