Repatha side effects not believed

Repatha for 16 months and results are amazing however, leg pain, calf pain, started 3-4 ago.
Sore, stiffness in thighs and calves.
I won't mind so much but my doctor insists it is NOT related to medication.
I have statin intolerance, my blood work with geno test shows this.
Why does my doctor not believe me when I say I'm having leg pain suddenly after no other apparent reason?
Am I crazy, am I wrong? 60yr old male with CAD, CAC score over 2k but no blockage all less then 70%, no chest pain.
We believe my 1 of 4 parathyroids, remove in 2001, caused calcium to enter blood was having very high serum calcium levels before being removed. Still have 3 parathyroids with not ill effects but damage has been done.
Can these side effect appear months later as mine have or I can it be something else?
