Still going to go with my original assumption, ask your GP or doctor about this

E3 wrote Hey there man, you need to get yourself down to an ER

From what you described it sounds like you have a low-energy compartment fracture

Basically over time there has been pressure building up in your lower leg between the muscles

You'll be fine should you have it treated in time should it actually be a compartment fracture

If you've noticed any numbness/paleness/tingling you're at the stage were if you don't get it seen to there is going to be some major complications, loss of use/nerve damage/muscle necrosis(death)

Slight shit news, if it is a compartment fracture you will need a fasciotomy basically they slice into the four individual compartments to release the pressure, of course you will be under anesthesia then afterwards pain meds, you'll have some big ass scars though for the rest of your life

Please note med student vs doctor/rheumatologist

They are going to give you the advice and checks you need I'm just telling you from the best of my knowledge what I think it is based on what you said

You probably needed an MRI not an X-ray. Go to a specialist.

If a doctor couldn't figure it out, TTG won't either.
