Get back to the things pain took away

A round of golf. Playing with your kids or grandkids. A long hike, a workout, a weekend in the garden.

Back and neck pain relief for Baldwinville and the surrounding towns for 20 years.

We look for the cause of your pain, not just where it hurts

Then we work on getting it moving the way it should again.

  • Find the structure that isn't doing its job. Pain usually comes from a stiff joint, an irritated nerve or a tight, overworked muscle.
  • Get it moving again with spinal adjustments and flexion-distraction, a gentle form of traction.
  • Calm the muscles around it with muscle stimulation and heat or ice.
  • Keep it working at home with exercises picked for you, plus nutrition to support healing.
  • See it for yourself. Short, state-of-the-art videos show what Dr. Mexico found and how he plans to fix it, so you understand your pain and why each part of your care matters.

Structure drives function

When a structure isn't working right, you feel it.

Every structure in your body, from each joint in your spine to the muscles and nerves around it, has a job that keeps you moving and pain free. Dr. Mexico's approach starts there. He looks closely at the structures behind your pain to find which one isn't doing its job, then builds your care around restoring that function. These short films show you what he looks for and how we treat it.

Want the full films? Patients get the complete videos for their condition, plus their exercise videos, to rewatch at home. Ask us at your visit.

What we treat most

From most to least common in our office.

Most people come to us because pain started getting in the way of the things they love. If yours isn't here, call and ask.

Your home exercises

Exercises picked for you, right on your phone.

Dr. Mexico will assign exercises for you to do at home, and you'll get a portal that links to them right on your phone. We'll also text you new exercises on a regular basis, so you keep making progress between visits.

Stop any exercise that sends pain down your arm or leg or makes things worse, and tell us at your next visit.

Nutritional Supplements

Your body is the master carpenter.

Dr. Mexico has spent the past 25 years studying anti-inflammatory nutrition, and it's a big part of how he helps patients heal.

Here's how he explains it. Your body is a master carpenter. It already knows how to repair a strained muscle, a worn joint or a tired disc. But even the best carpenter can't build without the right materials.

For your body, those materials are nutrients, and repair works a lot like finishing a puzzle. Your body knows exactly where every piece goes, but it can't complete the picture with pieces missing. Supplements don't do the repair. They supply the missing pieces so your body can finish the job.

Created by Dr. Mexico

Dr. Mexico invented and built Supplement Intelligence to answer a question most people never get asked: are your medications draining the nutrients your body needs? Many common prescriptions quietly deplete vitamins and minerals, and some supplements don't mix with certain medications.

You enter your medications, health conditions and symptoms. It checks them against nearly 20 years of clinical research, going back to eMedFX, the supplement-drug interaction platform Dr. Mexico created in 2007, and builds a personal supplement plan around them.

Your top 5 supplement recommendations

  1. 1
    Coenzyme Q10Priority

    100–200 mg daily

    LipitormetforminType 2 DiabetesFatigue

    Lipitor blocks a pathway your body uses to make both cholesterol and Coenzyme Q10, so supplementing helps maintain energy production in your muscles.

  2. 2
    Vitamin B12 (Cobalamin)Priority

    1000–5000 mcg daily

    metforminType 2 DiabetesFatigue

    Metformin can block your body's ability to absorb Vitamin B12, so supplementing helps prevent fatigue and nerve problems from low levels.

  3. 3
    MagnesiumPriority

    200–400 mg daily

    metforminType 2 DiabetesFatigue

    Metformin can lower your magnesium levels, and magnesium helps your body use insulin properly and produce energy in your cells.

  4. 4
    Vitamin DPriority

    2,000–5,000 IU daily

    LipitorType 2 DiabetesFatigue

    Lipitor lowers cholesterol, which your body uses to make vitamin D from sunlight, so supplementing helps maintain healthy levels.

  5. 5
    Alpha-Lipoic AcidPriority

    300–600 mg daily

    Type 2 DiabetesFatigue

    Alpha-lipoic acid helps your body use insulin better and may ease nerve pain from diabetes while supporting energy production in your cells.

Common questions

Where does the name "Mexico" come from? 🙂

Not from Mexico! As the family story goes, the name started out as the French surname Massicot. In French the final "t" is silent, so it sounds like "mah-see-KOH." Several generations ago, when the family settled in the United States, the name ended up spelled the way it sounded to American ears: Mexico. Fun fact: Dr. Mexico is actually 50% German, not French, and speaks fluent German.

Do I need a referral?

No. You can call or request an appointment directly. Some insurance plans have their own rules, so we'll check your coverage for you.

How do I book an appointment?

Call us at 978-939-8700 or send an appointment request on this site, and we'll get you scheduled. New patients, we'll set aside extra time for your first exam.

Does an adjustment hurt?

Not at all. Most people love getting adjusted, and plenty say it's the best part of their week. We warm up the area first with muscle stimulation and heat or ice, so by the time you're adjusted your muscles are relaxed and ready. Most patients walk out feeling looser, lighter and moving better than when they walked in.

How many visits will I need?

It depends on what you have and how long you've had it. Most new injuries improve meaningfully in 3 to 4 weeks, and chronic problems average about 6 weeks. You'll get your own plan at your first visit.

My MRI shows degeneration. Can you still help?

Usually, yes. Disc and joint wear is very common and doesn't always cause pain. Restoring motion and strengthening the muscles around it often makes a big difference in how you feel.

Do you treat car accident and work injuries?

Yes. We accept auto accident and workers' comp cases.
