Thimble develops wearable products that make pain relief as quick and easy as placing a band-aid. Our founder developed the first Thimble prototype to address his own chronic spine and wrist pain needs. After years of cycling through different pain treatments, he was frustrated by the lack of innovative pain products that thoughtfully addressed stubborn types of chronic pain.

We believe that people should be able to treat serious chronic illness as easy as treating a cut or a cold. No side effects, no surgery, no doctors — just go to your local Walgreens and pick up a quick fix. Our experience tells us that such simple solutions for pain, cancer, autism and depression are possible and will be developed in the near future. We are currently working to realize this vision for chronic muscle and joint pain.

We are currently in stealth mode. Please stay tuned for more information about our products.

Electricity has been used to relieve pain for centuries. Two hundred years ago, Ben Franklin invented a device he called the “electreat” to deliver electrical stimulation to heal muscle and joint pain. More recently, clinical-grade versions of these machines have been developed for use in pain clinics and sports training facilities.

Long-term studies have shown that electrical stimulation therapy, when accurately applied, can be very effective for relief from stubborn pain conditions like spine pain and arthritis. Despite common clinical use, existing stimulation machines have remained bulky, complicated, and too difficult-to-use for the average person.

Following 15 years of bioelectronics research and development, Thimble has discovered and developed a new approach for delivering electrical stimulation therapy that takes effect in seconds and is as easy as placing a band-aid. The result — a device that allows you to heal muscle and joint pain as quickly and easily as healing a cut.
