Hello to all! Im suffering from pain in my lower inner calf area. Im pretty sure its my Soleus Muscle (from looking on the net). I dont think its shin splints because I had that when I was in training years ago and it wasn't like this. I started training again recently after a period of being biffed (knee and back) and it came on initially from incorrect foot wear (trail shoes on road). I bought a set of MIZUNO WAVE INSPIRE 6 road shoes on advice from a running shop and for a short while they did the trick. I was smashing between 4.5 and 7.5 miles a night, at a reasonable pace with no probs. Last week I did my usual 7.5 mile route and felt fine. The next day I tried to run my 4.5 mile route and got about a mile in and started to feel discomfort. I cracked on for another 2 miles (legend!) and had to stop because the pain was again unbearable. This afternoon I tried again and the same issue after a mile so I stopped and walked back. The trainers are still fairly new (well under 200 miles used). I need to be fit for a January course so I have time for rest but not for injury. Im fairly concerned about it being some form of compartment syndrome. Any advice would be greatly appreciated! Cheers lads.
