It is wonderful to see so many sincerely concerned runners helping runners with their particular pain issues.
Your post caught my eye concerning your particular pain issues and the seemingly subpar results of efforts using rest, stretching and strength protocols as well as shoe choices. I can understand your frustration. When you finally address the primary cause of the pain, your repetitive use injuries will be resolved.
I love running and have been since my freshman year in high school. I am now approaching 68 laps around the sun and the journey has taught me "Gold dipped in Platinum" lessions about repetitive use injury and how to resolve them. I have been a specialist in myofascial pain and dysfunction for 16 years professionally, working with athletes from the high school, college, pro, Olympic and world record holder levels and I am an instructor of bodywork modalities at Healing Hands School of Holistic Health. The only reason why I mention my qualifications is so you can get an idea of my experience to add weight on what I am going to teach you as well as other runners reading this thread.
Physical Therapists, chiropractors, acupuncturists,etc., are wonderful in what they know and do to help athletes recover from injury but so often there is a missing step to recovery and that is identifying and directly manipulating and eliminating the cause of pain which are knots of habitually contracted muscle fiber areas called Trigger Points that cause a predictable pain pattern. When trigger points are present in the muscle, stretching and strength protocols are counter-indicated until these trigger points are reduced or eliminated. That is why often times, athletes feel worse when trying to initially solve their repetitive use injury by doing macro-stretching and strength work.
There are 5 steps to recovery : 1) Identify the trigger points and connective tissue adhesions that are causing limited range of motion and the pain pattern and restoring full range of motion through direct manipulation 2) Stretching protocols 3) Strength Work 4) Endurance 5) Maintenance. Most clinics are great at steps 2 , 3, 4.
Now, you can begin to understand why professional athletes are steering toward regular bodywork as part of their journey, self-treatment or/and bodywork sessions by a knowledgeable therapist. Also, more physical therapy and chiropractor clinics are hiring therapists that are trained in myofascial pain and dysfunction.
So, let's get into the op's pain issues. "Shin Splints" is an umbrella term used when pain presents on either the medial or lateral side of the tibia. Pain on the medial side is caused by trigger points in the soleus muscle, mainly. Pain on the lateral side is caused by trigger points in the tibialis anterior (compartmental syndrome), mainly. Your ankle issues are mainly due to trigger points in the fibularis longus, brevis, and tertius, as well as the extensor digitorum longus. You can eliminate these trigger points by consistent direct manipulation with a lacrosse ball on the floor, putting your posterior and lateral lower leg muscles on top of the ball and moving your leg side to side (medial and lateral) and up and down (distal and proximal). Also, there are other tools that are specific enough to be effective like the Theracane Max. Foam rollers are great for general work but not optimal enough for specific work. Do this before and after you run for 5 minutes or so. Your plantar fasciitis can be resolved by restoring suppleness to your calf muscles plus rolling your foot on the ball towards your heel and side to side. Do not put pressure and roll away from the heel. The fascia is trying to heal on the heel bone (calcaneus) so we are trying to help lengthen the fascia towards the heel. Also, purchasing a night boot to keep your ankle from plantar flexion while you sleep will help with the healing process.
Those of you that want to have self-empowerment in solving your repetitive use injuries, I recommend a book that I use in the classroom called "Trigger Point Therapy Workbook, 3rd Edition" by Clair and Amber Davies. This book is the doorway to solving your repetitive use pain issues. Make sure it's the 3rd edition. Here is a link:
