Earlier this month, I wrote an article titled “Tingling Sensation of Unknown Origin” where I talk about a new symptom that presented itself, and hypothesize that it may be a result of increasing milk thistle from 250mg to 750mg per day. While I cannot say for certain that my hunch is correct, I do feel more confident that my newly found nausea may indeed be caused by the increase.

This additional side effect started to present itself shortly after the dosage increase a few weeks back. I decided to take a few days off from administering my supplements—out of sympathy for my stomach—and noticed that my nausea disappeared. Considering the only thing I have changed recently was the milk thistle dosage, I have decided to revert back to 250mg per day to see if that is the issue.

While I was hoping to cross off symptoms as I progressed through the rounds, a new one appeared: parasthesia. What is parasthesia? From The American Heritage® Medical Dictionary:

par·es·the·sia or par·aes·the·sia (păr′ĭs-thē′zhə) noun A skin sensation, such as burning, prickling, itching, or tingling, with no apparent physical cause.

Without schedule or known reason, I get the sensation of my skin tingling on the right-side of my chest. It’s only a small section of my skin—maybe a three-inch diameter—that suddenly, and without warning starts to tingle. The duration is less than five-minutes and the experience is not unpleasant.

This new symptom first appeared around the same time I increased my daily Milk Thistle dosage from 250 mg to 750 mg. Considering the tingling sensation is located in the same place that my liver exists—excluding the fact that my ribcage lies between it—I have to wonder if they are associated.
