This is fairly common amongst PWP, and can also be a result of some of the meds we take. I tried the slow release pamipexole and found my sense of smell sky rocketed which was caused by the very ingredient that enables the med to release slowly I am highly allergic to, after only 4 days on this med I came home from work and walked into my kitchen and all of a sudden I found my sense of smell was so heightened I thought I was in a greasy spoon cafe. During a consultation with my PD specialist he said in all his years of treating PWP I was only the second person he had come across with that problem. Taken off that med back to to general release my sense of smell normalised about two week's later. My consultant ask me if he could write a paper on it. I agreed, my sense of smell now weak but that is much more acceptable to me. I have been told by others with our condition that the meds can help restore smell and taste, how true this is I don't know.
Hears hoping you find it is Lexi.
