Katherine's back no longer felt the way it used to.

Katherine tweaked her lower back while lifting weights a few months ago, and it had never been the same since. She experienced difficulty squatting, using the restroom, sitting for extended periods, and getting out of the car. This stiffness was a classic indicator of an L5 disc issue. True to form, Dr. Megan confirmed her diagnosis after a thorough analysis, involving a comprehensive review of her full spine x-rays, the use of her Nervoscope, and motion palpation. Following her lower back adjustment, Katherine experienced immediate relief.

Ryan - Neck Mobility Restored

Seemingly simple neck pain can be caused by a range of factors, however the origin is not always your neck!

Ryan came in with a kinked neck, but after seeing Dr. Fiona, a Gonstead chiropractor who adjusted his T5, his range of motion improved. Specifically, he was able to rotate his head to the right with greater ease, and he experienced a decrease in the tight feeling behind his shoulders and neck.

What Her Patients Think

" I was thankful to find Intero when searching Yelp for chiropractic help after hurting my back recently. They were the only Tri-Valley practice that could get me in on short notice as a new patient. 
Dr. Fiona has been wonderful in my adjustments and very responsive to my symptoms. I am now in month one of a three month plan and am feeling 100% better. They have also made progress on hand numbness I have had for some time while treating my back. Highly recommended for holistic care!"  ~ Chris H.

"Prior to becoming a patient at Intero Chiropractic, I was skeptical that "another" chiropractor would be able to help me with the constant debilitating pain and discomfort I was in. Boy was I wrong. Fortunately, their practice isn't like many other practices. There wasn't a time I left my appointments without feeling instant relief. It resulted in me feeling hopeful that the pain I was in for a long time would subside drastically. Dr. Fiona has really done her best at making sure I was able to get back to everyday duties with little to no pain after my treatment plan was complete. I would highly recommend this practice if you're someone or know someone who is living in any pain or discomfort; nothing about it will disappoint." ~ Felicia D.

What Her Patients Think

"After suffering a few months with sciatica pain I finally decided to see a chiropractor. Intero Chiropractic really stood out with their specialized approach to my pain. After initial X-rays, Ryan was able to provide a full detailed breakdown of my custom treatment plan. Ryan was great at providing great information and answered all my question. I got assigned Dr. Megan and we started my treatment. Dr. Megan always showed great professional knowledge, guided me throughout my recovery with expert adjustments and I can't thank her enough! After a few weeks I started noticing notable results and I'm 100% back to my old self and improved my overall spinal health. My only regret is not coming here sooner! Intero is highly recommended and I'm looking forward to my next visit!~ Alex A.

"Dr Megan is THEE BEST! I've had lower back/neck problems for 11+ years. I'm 3 months into a treatment plan and I feel a world of a difference. Quality of life has improved tremendously and I could not be happier. Highly recommend this clinic!" ~ Leah M.

What His Patients Think

"I came to Intero Chiropractic having severe sciatica pain for six weeks and was unable to move without flinching in pain. Alex has been adjusting my spine for four weeks now and I’m finally out of constant pain and can walk with ease. Alex was able to target the exact spot that needed adjusting. I’m so thankful a friend recommended Intero Chiropractic to me!~ Andrea C.

"A huge thank you to Dr. Alex for giving my spine and shoulder the best care. I started with Intero in September of 2022 and now in May of 2023, I feel so much better. I just saw my beginning and recent x-rays and can see the difference! I was feeling it already---able to walk without pain, teach Zumba and yoga with so much less pain. My case manager Ryan has been awesome, also. If I could give them 100 stars out of 5, I would.~ Bestey M.

"I am infinitely grateful for all the professionalism in my treatment and improvement process. I really felt great results from my first visit, helping me sleep better, even the neck and back pain that I was suffering from disappeared. I also thank Dr. Alex for his patience, good treatment and attention at all times of my assistance. I recommend 100% your attention. Thank you very much for everything 🙏🏻👌🏼👏🏻"         ~ Cinthia M.
