I saw my physio on Wednesday. As suspected, I have a small tendonopathy on the inside of my right achilles tendon. He did some work on it and prescibed some eccentric exercises in the form of slow heel dips - 3x20 at 20 sec per dip - and ice massage. All this I was expecting, but I needed to hear it from a professional as well as get advice specific to my condition. He also said that my back soreness is probably due to overcompensating for the achilles soreness, so he recommended my usual stretching regimen to help with that. Interestingly the soreness was located in the iliosacral vertebrae rather than the lumbar vertebrae, further indicating that it has nothing to do with my spondylolythesis.
WARNING: Bodily functions discussed. So to the exercises and massage. The first few days went OK, but then late Friday I started feeling bloated and tired. I think I had some digestive issues resulting in constipation. I felt like crap all yesterday and I've hardly eaten anything all weekend. I've been burping and farting all weekend and haven't felt motivated to do anything. I couldn't even eat all of the lovely dinner my wife prepared last night, much to her dismay (and in shame I slept on the couch until late night when I finally crawled into bed). I'm feeling a lot better this afternoon. I've cleared most of the backlog so to speak, and I'm less gassy, although it is still there a bit. I started eating LSA on Thursday, I wonder if that has anything to do with it? I'll cut out the LSA and eat plenty of fruit and veg - if I can fit it in - and see how that goes.
I'll get in some more dips this afternoon and some more icing. My back soreness has mostly gone away so I can get back into the strengthening exercises soon too. I'll update in a few days or after my next physio visit on Wednesday.
