Hello,
From the symptoms, it looks like pompholyx to me. The exact cause is not known and excessive sweating can be one of the reasons. But some triggers like allergic reaction to soaps, detergents, foods, latex, nickel etc may trigger the symptoms. Apply some calamine lotion on the affected area and keep the area well moisturized. Use only thin applications of moisturizer ointments as excessive amounts of ointment may restrict breathing of the skin and aggravate the condition.
Topical steroids can be applied but they are available under prescription. Moreover to prevent infection, topical antibiotics may be needed. I suggest you to consult a dermatologist and get it evaluated.
I hope it helps. Take care and regards.
Thanks for the reply. Since posting that message I have cut all nightshade foods from my diet (tomatoes, peppers, chillies, tomatillos, potatoes etc) but I am still using all the spices I used before and I have noticed that the blisters are going away and the skin is slowly starting to heal. I cooked something a few nights ago and I used a tin of tomatoes and the following morning there was a few itchy blisters on my fingers - so i decided to eliminate all the nightshade foods for the time being to see if that helps.
Kind regards.
You may have Dyshidrosis...
Dyshidrosis (also known as Acute vesiculobullous hand eczema, Cheiropompholyx, Dyshidrotic eczema, Pompholyx, Podopompholyx) is a skin condition that is characterized by small blisters on the hands or feet. It is an acute, chronic, or recurrent dermatosis of the fingers, palms, and soles, characterized by a sudden onset of many deep-seated pruritic, clear vesicles; later, scaling, fissures and lichenification occur. Recurrence is common and for many can be chronic. Incidence/prevalence is said to be 1/5,000 in the United States. However, many cases of eczema are diagnosed as garden-variety atopic eczema without further investigation, so it is possible that this figure is misleading.
This condition is not contagious to others, but due to its unsightly nature can cause significant distress in regard to social interactions with others.
The name comes from the word "dyshidrotic," meaning "bad sweating," which was once believed to be the cause, but this association is unproven; there are many cases present that have no history of excessive sweating. There are many different factors that may trigger the outbreak of dyshidrosis such as allergens, stress, or seasonal changes. Emotional stress may also further aggravate the condition.
CAUSE:
The principal causes of dyshidrosis is an allergic reaction to the colonization of any part of the body by a yeast, mold or fungus.
TREATMENT: use an antifungal cream such as Clotrimazole.

As a follow up...
If you do not see results from Clotrimazole...
Try Undecylenic acid...
Undecylenic acid is an organic unsaturated fatty acid derived from castor oil. It is the common name of the 10-undecenoic acid, (CH2CH(CH2)8COOH). It is used in the manufacture of pharmaceuticals, cosmetics and perfumery, including antidandruff shampoos, antimicrobial powders and as a musk in perfumes and aromas.[1] Undecylenic acid is produced by cracking of castor oil under pressure.[2]
Medicinal uses:
Undecylenic acid is a natural fungicide and is FDA approved in over-the-counter medications for skin disorders. It is the active ingredient in medications for skin infections, and relieves itching, burning, and irritation. For example, it is used against fungal skin infections, such as athlete's foot, ringworm, jock itch or Candida albicans.[3] When used for jock itch, it can result in extreme burning, as the skin is rather sensitive. It is also used in the treatment of psoriasis.[4] Undecylenic acid has antiviral properties that are effective on skin infections such as herpes simplex.[5]
The mechanism of action is unknown.[6

I suffer the same since I was a child and I always thought it was some sore of fungal infection.
I am Asian and being a kid I remember favor only vegetables and had no taste for any meats nor lacteous products.
We moved to Central America in which the variety of vegetables are limited. I remember I had an extreme episode of exacerbation of the itch insane blisters that I never forget. Alone with continuous constant episodes like the one I have now throughout the years.
The doctors used to give me antihistamines and all types of cortiso creams to aliviate the itch.
It wasn't until when I moved to USA in 1996 which the episodes calm down.
Back then, the other white meat ( pork) was not as popular in US.
Several years when by until I had pork and my itchy blisters return.
Once my system eats pork and gets sensitize to it a chain reaction occurs.
I get then itch to beef, to washing and touching the fat of chicken before cooking it and to all raw animal fats that touches my skin.
I remember an event few years ago in which After eating French fries from Mc Donnald, I had blisters in the same fingers that touch the fries.
I was clueless since potatoes and vegetable oil are not animal products.
Setting in one of my lectures with mostly vegetarian Indians, a topic of lawsuit came across that Mc Donalds was sued because it was adding pork fat to the oil they use to fry French fries.
Then, I understood.
My theory is that my body is not able to metabolize the toxins and byproducts that are formed from it, therefore my immune system reacts to animal products ( specially pork) as an allergen.
This is now 2015 and last week Memorial weekend I wanted to have a little taste of bacon in my super homemade grilled BLT. Needless to say, I am itching with blisters.
It is also appears in other parts of the body but it is much more suttle.
It seems to settle where the blood circulation is less and it is recurrent in the same nitches.
Now that my system is sensitive, the itchy blisters are appearing also after a slice of charp cheddar cheese.
I use a medicinal Chinesse root to what I called detox myself from all impurities and go in a diet of no meats while I detox.
I hope this helps
