Hi Carla - you are not alone, happens to many! Unless your footwear is a little too short or narrow the big toe pain can usually be traced to the wrong shape footbed extending your foot incorrectly, is a referred pain - that strong curve along the sole 'behind' your big toe, it needs to be properly shaped and supported - so ... try walking in different lightweight footwear, your most comfortable, and see what happens then. If you don't have alternative footwear try this. Remove the laces and then put them back but miss out the first two or three lace holes - this will allow the front box to open and be more flexible, giving that big toe more room.
Re your knee ... best option is a doctor who will refer you to a physio or also offer an x-ray of it.
But, on Camino I have found that there are three main problems that cause pain in a knee ....
Pack too heavy - remember, every ounce on your body pushes down through your knee joints and as only one foot is on the ground at any one time the whole weight goes through one knee.
Walking speed, gait. Roman legionaries marched by short high stepping rather than low long stepping, and they could go all day over all terrain and carrying heavy loads. Shorten your step length, shorter steps. Slow down.
Swivelling. Your main clue is that it is 'uphill and downhill'. The knee is designed pretty well to move forwards and backwards but not so well to swivel when under load/stress, especially when combined with walking forward on hills. On certain terrains you cannot stop that swivelling and that causes tensions on ligaments and tendons - nice sharp pain.
The only way to help this is to encourage (limit) the knee not to swivel and a good brace, with metal hinges either side is an excellent piece of equipment. Soft stretchy sleeves have no effect whatsoever, except for making one feel warm and as if one is doing something.
- But - first stop is your doctor.
Actually, first is to stop walking until after you have seen your doctor .. you don't want to make it worse now
.
As an aside - many people swear by certain joint supplements such as Turmeric - could be worth Googling?
