What causes pain and itchy blisters on the toes and feet?

I ve been suffering with pain in my feet and toes for 4 months. Severe electric shock type pain which radiates into my legs and will cause my feet to jerk, especially when laying or if feet are elevated. The jerking & shock feeling begins in the left leg s big toe, takes over the foot and leg, moves into the right foot/leg, and can go into my arms/wrists, making them jerk, too. Very painful when this happens and I m unable to remain in bed or in certain chairs. However, with Neurontin, the shocks are more contained and the shooting, electrical, pain remains in my toes and feet. One foot has numbness and feels swollen on the bottom, and toes on both feet are painful even to the mildest touch. During the past 3 weeks, small, painful, blister-like bumps have begun on my toes and face along the hairline. These blisters aer very painful, seem to be slowly spreading and become itchy at night. All symptoms are worse at night. I ve had tests run in the past which showed nerve damage in the C3-C4 area, though admittedly, these tests were done about 10 years ago. I m unsure if I m dealing with the garden variety of neuropathy or if it s diabetic neuropathy. I haven t been tested for diabetes in at least 15 yrs, though my mother became diabetic in her 70s. She was diagnosed with Restless Leg Syndrome many years before diabetes, though I m suspicious that it could have been a tell-tale symptom with which she wasn t familiar. Your thoughts on my pain and itch issue?

Hello,

Electric shock like sensation may be due to spinal root compression at the cervical region or lumbar region.

Other possibilities like multiple sclerosis or epilepsy (Jacksonian March) or peripheral neuropathy.

Need MRI brain and spinal cord, neurophysician consultation.

Blisters may be due to eczema or autoimmune bullous lesions or contact dermatitis or drug eruptions.

Use antihistamine or local steroid under your doctor guidance. Please consult your dermatologist he will examine and treat you accordingly.

Hope I have answered your query. Let me know if I can assist you further.

Take care

Regards,

My toddler has blister like things, as I do not know what to name them at this point. I have taken him to Emergencey room (pediatric) side at UTMB in Galveston, TX & was told he has hand foot and mouth disease. I can see why this conclusion was made. He had thrown up 1x day prior, had a fever that evening too & the bumps were located on palms of hands, soles of feet, and mostly on the toes, top of toes and end of toes, forming a clear- white blistering appearance with some much larger than others. He is having a rough time. I believe he is in pain and am absolutely certain of the severe itching he is experiencing. He was so angry that he began running around the house throwing his toys and hitting me. I made sure he was safe and reassured him this would pass and rang the dr again, questioning the hand foot mouth diagnosis. I was reassured this was what we were dealing with. I again questioned it later on during same day and again was told the same thing. Well- now 2 days later I am seeing these bumbs spread to legs tummy with the feet worsening. His mouth has a few flat red spots that may have ruptured, but do not know if a small blister was ever there, if there was it was overnight and I didn t see it. I keep thinking it is something other than hand foot and mouth, and then I go back to the vomiting fever and listlessness with the areas which this rash began- the feet hands and outside of mouth- none inside although. So it fits, all except the relentless itching. I just do not know what to do! I do not want to wait if it is not what I was told, especially with my son being miserable. I do not want to wait it out only to realize, oh it may be something different as this is only getting worse. I feel helpless and I do not want to be a disservice to my son by not trying any and everything until we figure it out, but also do not want to be a crazy lady if I am being impatient. Thanks in advance!

Good morning...My name is Heather & I am trying to help someone very near & dear to my heart figure out what might be causing some issues they are experiencing...Hopefully you can be of some assistance...for over a year now, they have had reoccurring episodes (every 2 months or so) of tiny, extremely itchy blister like rashes on the exterior of his heels, also on the outer edges of the soles of his feet but not underneath on the bottom of the soles & between his toes on both feet, on the upper buttocks (above & slightly down into his butt crack) & in his upper groin/pelvic region...he complains that the itch is almost unbearable & when I observed these areas he had scratched them so much that it s caused some scabbing...when popped, the tiny blisters release a clear fluid/pus...we ve tried so many different things such as creams & lotions with no real results...like I said these episodes have been reoccurring for some time now & we have racked our brains trying to figure out what might be causing their on-set but again are dumb-founded...I should inform you that he has been regularly checked for STD s & ALL tests have come back negative...in the past he had tested positive for H-Pyloria but was successfully treated...any help or insight into this bizarre nightmare would be greatly appreciated!...a little more information on him...Black/Hispanic male...50 years old...good health...takes anti-anxiety & acid reflux medications daily...never has been a drinker, drug user or smoker...
