Hi,
I have experienced hundreds of episodes like you are describing.
I first started to have swelling episodes with my period every month, since about 20 years of age. I am now 53. For most of my life I thought that thought this was severe PMT. It was also always followed by 3 days of migraine. My legs would swell for 3 days before going down over 3 days. I took fluid tablets to control the symptoms.
Gradually over many years the fluid became impossible to control and my periods got closer and closer together.
I had a hysterectomy at about age 48 and begged my surgeon to also take out the ovaries, so as to reduce any hormonal ambiguity.
Unfortunately the surgery made no difference at all, and the swelling episodes got worse and closer together.
I now feel with a lot more information, that I was probably having episodes of mild but chronic SCLS. I definitely however feel that is has been triggered by hormone levels. I think the migraine is caused by cerebral edema. It starts at the peak of fluid just as fluid starts to recede. Now fluid only goes from 100% to 75% instead of back to 0% as it did in the past. This makes it difficult to get a proper diagnoses.
Additional information is that I was diagnosed as Hypothyroid at about age 48, and all my hormones levels are at the bottom of the range or under, but not quiet bad enough to be called hypopituitary. I take very high dose direct T3 medication but still have low levels and seem resistant to my own hormone and additional hormone medication. This is still under investigation.
I am happy to email with anyone else who has experienced a hormonal connection with their SCLS. I is nice to know i am not alone in these experiences.
