Welcome to NeuroTalk:

Sounds like you need to see a good podiatrist.
That foot going off at an angle, can be fixed with bracing.
I don't recall the name of the condition, but it involves the tendon and muscles of the lower leg. Also it sounds like you have hammer toes, and those can be fixed too. Sometimes only wearing proper shoes with a large toe box and also taking some magnesium supplements (but NOT the OXIDE form), will relax the hammer aspect. They happen when the muscles in the lower leg spasm and don't relax properly.

Here is an excellent website with diagrams and tons of information to guide you:

And here is my magnesium thread:

You can try soaking those feet in epsom salts twice a day.
Use about 2 ounces of salts in a dish pan, with warm water to cover the feet, or 6oz or so in a bath tub for a longer soak. Epsom salts make things slippery so be careful in a bath tub.
This will help magnesium get into your feet more quickly than an oral supplement at first. If you have poor circulation to the feet, soaking will open that up so oral supplements can then get down to them better.

This would be a good start for you.
