Hi Sammiejane
Did you get this after just the first application? How long have you been taking the gel?
If one day then I imagine it will be something else. Keep an eye on it and if it carries on do tell your doc. Arm and neck pain is a side effect of the gel and if you get these you must tell doc immediately. X
This is not a usual side effect as far as I understand. There are warnings on all HRT (and as with all drugs) that a doctor should be consulted in the case of various extreme symptoms. The side effects in any case would not be that local. Localised side effects are to do with skin irritation at the site of application.
Sammijane if you are adding progesterone at the same time you won't know what any side effects or positive effects are due to this time. If you want to try progesterone which you don't really need in terms of your body, but want to try perhaps because of its sedative effects eg as a sleeping aid, it would be better to settle on the gel first - and start low and slow and build up gradually until you reach a level that controls your flushes and then if you are wanting to try the progesterone introduce that very slowly.
Utrogestan always has an effect on my bladder - I use it vaginally but always makes me want to pee more and bladder more irritated.
