Pain in top Right shin…

Hi guys, 23yo male here from the UK, in the process of getting diagnosed after 4 years of symptoms. Seeing the rheumatologist in end of may beginning of June.

Classic symptoms, back pain at night, joint pain especially in the knees. Sacrum burning and buttocks pain. It comes and goes (flares for months then dies down)

However a new pain is making me worried.

I have a really bad pain at the top of my shin it's sharp and hurts. When resting and when moving, My shin on my right leg hurts overall but specifically at the top of it.

Does anyone else get this type of pain? Any way to ease it?

I can never tell if it's something new or attributed to this disease.
Thanks you in advance.
