Dear all
Thanks Pierre about for these helpful comments about Injecting
intralesional antimony. I agree and would point out that injecting small
volumes is important. The pain is also quite brief. We use weekly
injections and i find that substantial healing occurs between
injections.

In my personal experience intralesional antimony is not more painful
than injected anesthesia. Injected antimony is not painful by itself
upon injection. What is indeed painful in tissue distension linked to
the injection of fluid - this is why injected anesthesia is useless when
performing IL injections of antimony. Epicutaneous anesthesia with
lidocaine cream, superficial short cryotherapy just before injection
(that also increases efficacy as mentioned in a previous message), small
needles and slow injections reduce the negative reactions of patients of
all ages. There is no residual pain after injection. In L. major CL we
rarely need to repeat the procedure more than 3 times (when cryo is used
along). Yet I agree that this is more than the single session of
thermo.

Each local method has therefore its strengths and weaknesses and none
of the methods creating pain and requiring specific material or devices
are optimal in the fields, which emphasizes the need for effective and
widely  available ointments or oral agents. I completely agree that this
is particularly true for children.
