Parietal lobe epilepsy or parietal lboe dysfunction

Is there anybody here that could eplxain how to get properly diagnosed with this or to at least have a check up for it. I have read eeg's many time do not pick it up. I have read articles on dysfunction of the parietal lobe and I think there is at least dysfunction in them. I fail the mental rotation tasks which I also read are associated with right parietal lobe dysfunction and I think some times I have seizures after trying to do so. It makes sense to me as well. damage to the right parietal lobe can result in OCD one case of OCD was caused by a hemmorage in that area. The annoying part is actually trying to explain it to people and for them to understand how much it impacts me. I can not do daily tasks like washing the dishes. Doing them hurts my brain.Despite this somehow I walk the dog and have no pain. Is there some way people try to diagnose this condition?

here is the article about the rotation task that I fail.
