I had a grand mal seizure about a month ago while I was on my period. I've never had seizures before, but I noticed that the blood flow from my period was really heavy when I woke up. About a week after the seizure, I experienced a slight tightness around my navel. I'm noticing now that there is a lump or hardening sitting right above my navel. The navel itself looks like its beginning to bulge a little as well. I'm told that it isn't likely to be a hernia because those take a very long time to develop. Please let me know if there are some possible suggestions for this and if its reversible. Thanks.
