I've dealt with Achillies/plantar F for nearly 20 years. Cycles of getting in shape, then the pain comes back....I am still not cured but I have spent the past 2 years rebuilding my body from years of poor nutrition and over training. Here is what I have done that seems to be working (it's just taking a long time due to trial and error and fixing 20 years of poor biomechanics).
1. Chiropractor regularly saw her every month, and more in the beginning, now I am down to once ever six months if I keep up on massage.
2. personal trainer- to help with learning how to lift heavy (where the Fvk was this knowledge back in early 2000's when I was running in college?!) I used a trainer for about a year. Important lifts to learn or muscle groups to target: Deadlifts, hip thrusts, gluteus medius basically any banded exercise where you're activating and working your hip adductor's and abductors/ glute med, give more attention to working your entire posterior chain from the back of your neck to your soliuses.
2.5 Nutrition- almost forgot... When I started lifting heavy I also started to eat my body weight in protein every day
3. Soft wave therapy- After I started getting stronger I felt I was hitting a plateau and I was lucky that my chiropractor also started offering shockwave therapy a.k.a. soft wave. they did a lot of sessions on my hip more so than my PF or my Achilles which was a surprise. But I found I eventually hit a different Plateau with this as well.
4. Physical therapy- one who looks at your entire body... he made some great adjustments to my metatarsal/tarsel articulations so I could close the angle a bit more between my shin and the top of my foot. After this adjustment I felt a significant more range of motion in my arm swing range of motion- a reminder that everything is connected! he also worked on my SI joint, hamstring insertion, and sternum/rib cage (I had a pretty bad fall off a horse a few years ago)
5. Compression boots. I bought the norma tech compression boots. what might be an important tip for using these is to extend your legs out as far as possible and as straight in alignment as you can as the compression gets tighter and tighter as the boots fill with air.
5.0 massage- semi regular full body massages....
6. total ankle strengthening exercises not just calf raises. I think this is my final key to curing my Achilles/PF. My hip and glutes are way stronger with much improved range of motion with all the deadlifting and hips thrusts I've done.but my lower leg is still on the stiff side. I've never had shin splints but I wonder if my weak shins show up as sore Achilles. I started putting weight on the top of my foot and lifting it. Also started using a balance board...single leg balance exercises rotating the board with CONTROL in a circle. It's difficult and I definitely feel my hip stabilizers starting to fire!
Other important notes: I've barely run for the past 2.5 years while trying to strengthen my weaknesses. I have a really great running community nearby and am dying to get back to groups runs, but also not going to repeat the same injury cycle. I've turned all my passion for running into lifting and riding horses (dressage). It's so important to have another activity while you cure you body! *I lift with a lot of focus and control. It's critical you are engaging the correct muscles while lifting and utilizing the entire range of motion. Mirrors are key when working on balance and straightness. A personal trainer was a game changer for me, but so was YouTube channels discussing proper lifting form. I follow a few body builders social media, they are especially lifting/technique/anatomy savvy!
