Itchy Heat Bumps
So last year, around the same time (2015), I had this same ( Bumps ) issue. I think it stopped when I threw away the vitamin tablets I got from the health store.
Now known as = Pompholyx (dyshidrotic eczema)
But now it has started all over again, it’s been a few days, and now it’s getting more itchy, almost unbearable at times, so I’m online searching for clues.
About a week ago, I bought the Swisse brand IMMUNE tablets and the Swisse brand SLEEP tablets, but I’m not sure if the (Heat Bumps), as I call them, started a day before or a day after.
I just can’t recall which day it started, so I’m going to stop them and hope that it’s something in those, that’s the cause. It’s worse on my right hand atm, which also sometimes feels like there’s something moving under my skin.
This is the closest I’ve gotten with online searches, but it’s very itchy

I’ve asked a couple of doctors, a couple of pharmacists, and a few other people, but the answer is always different, so I don’t think I can trust their judgment anymore until some sort of test is done to determine the fact and then the cause.
UPDATE: So it turns out that after a week of not taking the supplements, my hands are now better 😉

UPDATE A YEAR OR SO LATER: It turns out from the link above that it’s most likely Pompholyx (dyshidrotic eczema)
UPDATE: 21-8-2019
I’m sorry to say I have not defeated this problem, and it did come back last year in the summer of 2018. I blended certain healing vegetables, mixed them with apple cider, and placed my hands in them for 30 minutes, and it got better.
This year, in the 2019 summer, I have got them again, and as an added bonus, it’s also appeared on the sides and bottom of my big toe on my left leg. I have watched a couple of new YouTube videos on the topic and was almost convinced it was Hand, Foot & Mouth Disease until I got this video here.
After reading the comments, I’ve come to realize so many people are having this issue, and it’s amazing that no medical company has seriously looked into what the liquid inside the bumps is and how they work to determine what causes it in some people and not others, and therefore find a permanent solution.
Because the thing is, when you’re having an eruption, you feel like giving all your life savings to be able to never have this happen to you again, and that stress just makes it worse, so you feel like you would even cut your hands off.
Anyway, after reading the helpful comments on this video, I have just rubbed coconut oil and neem oil on them, and they have stopped itching within ten minutes. I hope it works and gets rid of them, as this would be an easy, inexpensive, and quick solution that anyone can try anytime and anywhere.
Cheers.
Update 2020
I had 2 mild eruptions twice this year, months apart, on my hands,
I found a new useful website dedicated to itchy skin issues.

Update 2021 
I have found a good dermatologist, and she is not like the rest.
She prescribed me these medications below, and every time I get an eruption, these medications dry and clear up my Itchy Heat Bumps within a week. “That’s what I call medicine, that works within a week, not months :).”
Solution:
How I use these medications:
Augmentin – Take for 3 days 1 tablet in the morning and 1 tablet in the evening, then take 1 tablet daily for the next three days.
Terbiderm Forte – 1 tablet a day for a week
Kestine – 2 tablets a day for a week.
Fucidin Cream – use a few times a day whenever I feel like it, for a week
Terbiderm Cream – use a few times a day, whenever I feel like it, for a week
Hope this helps anyone suffering from this problem. We still don’t know after testing what it is and if it’s an allergic reaction or a skin problem, as skin and fluid sample tests revealed nothing whatsoever.
31/2/2022 Update:
It came back! Doctor Confirms it’s pompholyx
I’m sick and tired of it, I’m going to use the same treatment as last year, plus the script for this year was these two and a milder soap and moisturizer.
This is also known as vesicular hand/foot dermatitis or dyshidrotic eczema
2023 – Still happened 5 times & I used the same meds.
2024 – Still using 2021 medications as a solution, I don’t believe the topical creams do anything. 
2025 – Forgot to write it down, but I started using 70% isopropyl alcohol, which did not prevent it, but when it started happening, it did dry it out pretty fast.
2026 – Still using 70% isopropyl alcohol, working great. I now use 70% isopropyl alcohol to disinfect my hands as soon as I come home, and after shaking hands with anyone or cleaning the house, and after chores, I probably clean my hands with this at least 5 times a day. This is in addition to washing my hands with Lux soap even more times a day. And the Itchy Heat Bumps do come once or twice a year, but this stuff clears it out in days and does not even reach the excessively itchy stage.
