Foot Pain, no answers for 8 weeks - help

I’m a sprint hurdler (male) and have been having foot pain for about 8 weeks, seen multiple people and clinics and I keep getting vague answers. I’m just looking for guidance here, or even just a rough direction that I should look in.

details:

- pain in in the middle upper part of the foot, around metatarsal one

- I think, the pain is coming from the cuneiform bone, or the joint between metatarsal one + medial cuneiform

- only pain when pressure is on the foot, ie, running, walking, single leg hopping

- pain is 3/10 when sprinting. NO pain unless foot is loaded

- Had MRI, came back completely clear

- dull pain, not sharp pain

- pain progressively got worse for about 2-3 weeks, before I had to stop training

- no visible swelling anywhere on foot

- injured foot arch, very slightly collapsed compared to the other

- no clicking or anything usual, foot operates fine apart from the pain

i just want any help, I feel like I’m trying everyone and everything and nobody knows what it is
