My husband has been having major head aches. We took him in an d they found a cyst on his brain. They said that he's having cluster head aches. Now he has starting loosing strength on his left side, had mood swings, bad short term memory loss, and most recently is swelling in his lips and hands. What's going on w him? He has seen many specialist and no one can figure it out. Some say the cyst need to go and others say it's not the cyst. We are lost... The last neurosurgeon said that he didn't think it was the cyst but that there's def something wrong and the local docs need to start from square one to figure out what's wrong.
