I have had Achilles’ tendinitis a few times over the past several years. Each time I have gone to this place called Pittsford Performance Care here in Rochester. They specialize in neurologically based treatments and modalities, partnered with chiropractic medicine. Depending on the severity of the tendinitis I have had to go for 2-3 treatments and it is completely back to normal. I’m back to normal training within a week of the onset of I get in right away. The first time I went I had been out of running and cycling for 2.5 weeks. They had me back up and training within a week.
It is a very unique form of treatment that I’m lucky to have available here. I would check out their website and read up on what they do and then see if there is anyone local to you who does treatment like that. If not, you could always visit Rochester and get treated.
