Yes I am going along with you here...it sounds right. Too, help this as soon as you think of it (all the time) either use a towel wrapped around the foot and pull it to you to point the 'toes to your nose*...this is stretching out the 'achilles tendon' in the calf that is pulling on the tendon.
Another choice is to go to a wall and stand back about 3-4 shoe lengths and lean in to the wall at at angle. Keeping the feet planted to the floor feel the stretch of the calf that way. If not enough for you, move the foot outward more with the 'lunge' effect to do the same.
For my situation with the trigger points, I have had the calf injected as it was just that (a trigger point) in the calf that was making the spastic calf muscle and this relieved it. Warming the calf before these attempt may make it easier to respond.
I can remember early on being crippled to get up from break at the hospital....when you sleep the achilles shortens even more.
As a rule our muscles are lazy guys and NO ONE wants to work!! My trigger for that was I started walking track and I didn't stretch before or after...so I got into trouble. I also had podiatry in the last 3 years or so inject the heel to free me up to really work at the stretching. (TOUGH SHOT) and I do shots all the time.....but it was instant help to do what I had to. Then I had neurology find the muscle trigger and wa-la fixed.
But that is my story. Try all the exercises first and then podiatry can take you further. He may want a good arch support in your shoe too...this helpful to pitch the whole leg right.. No arch and you tend to slide outward and stress the knees.
I am seeing that in your statement too. You are favoring the foot and it then goes to the structure connected to it as you have changed what is norm. (remember the song "the knee bone is connected to the leg bone..the hip bone conneceted to the the leg bone and on and on" IT IS SO TRUE...I swear they all talk to eachother....good luck I know it is painful.
The towel/rope/chord trick to pull the toes foward can be done before getting out of the warm bed, have it on the bedside and stretch out before you stand. IT is painful when you start. IN THE SHOWER..back to the water and warmed...lunge to the wall....that was my best 'win' moments.
All my best...Nancy B
