Not much info to go by here,so my answer is a 'general 'statement'.
1-Do not self prescribe
2-Ask specific questions like these to your practicioner he/she has taken your full case history and fully understands the process of dosing/dillutions.A discussion forum knows nothing about why this remedy was prescribed,does not have your full case to go by.
3-not wise to jump to verry high potencies without supervision- you may have severe aggravations,yes correct.
4-for detailed info on potency prescribing methods see link;
