can’t comment on the gynae issue without more info but it is quite common in gynae issues for various meds to be tried and some do make some people worse.
if her meds are hormonal contraception of some kind then it may be worth asking to try a different brand of the same meds or different meds eg combined pill etc.
in theory if you are in pain the gp should be prescribing to help you, in practice…..
if her pain is uterus related then there are painkillers that are often prescribed for gynae issues - mefenamic acid and tranexamic acid are two I have been on.
there are issues with getting painkillers prescribed these days as opiate based painkillers (codeine, tramadol and similar) are only supposed to be prescribed at lowest possible levels due to risk of addiction.
in addition painkillers in the ibuprofen family the doctors are now wary of because of evidence of stomach problems so the guidance is that they are supposed to prescribe stomach “protectors” like omeprazole alongside but also they are under pressure to reduce prescribing of these drugs.
so … this basically leaves nothing, myself and lots of my friends (I’m disabled) have come under a lot of pressure to reduce painkillers.
however it’s not ok to leave someone in pain and if she really really hassles the doctors they will prescribe.
over the counter she can get paracetamol, ibuprofen and co-codamol which is paracetamol with codeine.
ask for painkillers and push that she is in pain and they’ll probably prescribe mefenamic acid or similar and stomach protector.
re the second opinion, if she has gynae issues the treatment is often some kind of hormones. Some of these are not suitable for eg people with a history of breast cancer so it’s possible that this was what the consultant was talking about?
biopsies are usually for cancer situations.
