Hello, thanks for using HCM.
both belong to a group of drugs known known as statins with basically functioning through the same pathway in the body. Statins are known to cause groin pain, muscle pain
and joint pains
as side effects with the occurrence of this necessitating visiting a doctor.
However, it is less likely that the pain you experience was due to the change in drug since both belong to the same class and the symptoms you experience have not continued even though you have continued the drug.
Possible causes of groin pain include injury to ligaments and or tendons of the hip joint ( which could appear immediately after trauma or some time later), adenitis ( inflammation of lymph nodes), renal stones
, hernias etc.
Best regards and hope i did help.
