Can dehydration cause pain between my big toe and second toe?

Hello,

Welcome to icliniq.com.

I have read your query and understand your concerns. Thanks for the detailed information. This helps narrow things down. Pain between the big toe and second toe that appears while walking and feels like a "V" of pain could be caused by several possible issues, even without trauma or a history of foot conditions.

One possibility is an intermetatarsal neuroma, such as Morton's neuroma, which is usually located between the third and fourth toes but can occasionally affect other toes. The pain from this condition is typically sharp, burning, or tingling, and it results from nerve compression, which can be worsened by tight footwear.

Another potential cause is metatarsalgia, where pain in the ball of the foot radiates between the toes, often due to overuse, walking on hard surfaces, or wearing poor footwear. Web space irritation or callus formation might also be the cause.

When toes rub together excessively, such as when wearing sandals, it can lead to pain in the "V" area and may feel like walking on a pebble. Tendon or ligament strain is another possibility, as small muscles and tendons between the toes can become strained during unusual or excessive activity. Although dehydration and electrolyte imbalance are not usually direct causes of localized pain like this, they can contribute to muscle cramps, which tend to feel like spasms rather than pinpointed pain.

Some initial suggestions include checking your footwear to ensure they are wide enough and supportive, resting and elevating your feet, applying ice to the area for 15 minutes a few times a day, staying well-hydrated, and considering magnesium- or potassium-rich foods.

You might also benefit from gently spreading your toes or using temporary toe separators. An over-the-counter nonsteroid anti-inflammatory drug, such as Ibuprofen, may help if inflammation is suspected. You should seek medical care if the pain persists beyond a week, worsens, or is accompanied by swelling, redness, or numbness, or if walking becomes difficult or you feel instability.

I hope this helps.

Thank you.
