[|Human|] Hi, I have recently been diagnosed with a brain lesion (cavernoma). The symptoms I have experienced are numbness in my right arm and shoulder area. My question is: How likely is it that the lesion will bleed again once it has already bled. Also, what are the chances that I will regain normal sensation in my arm? Thanks for your help Slava Fisher
[|AI|]  Hello Thank you for trusting Chat Doctor If you haven't had any bleeding before, its estimated you have a less than 1% chance of experiencing a hemorrhage each year. If your cavernous has bled previously, your risk of having another hemorrhage is somewhere between 4% and 25% each year. However, this risk decreases progressively over time if you don't experience any further bleeds, and eventually returns to the same level as that of people who haven't had any bleeding beforeCavernoma walls are weak it causes rebleed and reabsorbed causes slowly increasing size. . So there is a chance of rebleed 4-25%.so chances of deterioration of symptoms. Please consult your doctor if symptoms deteriorating and new symptoms developed he will guide you in right way.
