Thank you to all who wrote back. Yes, they say it is reversible, and subsequent mriS have shown the bleed has stopped, no infarcts, no mass, but still "several foci of subcortical flair hyperintensity...stable," whatever that means (I am to see my doctor in 10 days). I am not sure how they know that the vascoconstriction has reversed unless they do another angiogram, which they are reluctant to perform, assessing me clinically and with MRI instead.
As you have all said, this is going to be a long-term heal, 'though I push myself to stay physically active. I had a very big and busy morning today and was popping analgesics to keep going, but am now exhausted, slightly nauseous and headachy, which seems to happen alot lately. Piratesbooty, I will be interested to see how things go for you as it is still early stage in recovery; yesterday was my six-month mark. Great that they found your trigger but sorry about results of stopping it suddenly. Are you on anything else for the RCVS or symptoms, indeed, do you have any symptoms like mine? Did your blood pressure spike, did you have headaches?
