Strong painkillers taken before PIP assessment

you don't need to tell them, if your  medication is prescribed they will know from the forms you fill in before hand because it does ask what tablets your on, how offen you take them

I didn't take my medication before assessment as I wanted to feel my pain so it could be seen.  Unfortunately it made absolutely no difference to the outcome. Had to attend tribunal where there was a qualified medic who understood my condition and was granted high on both mobility and care.
