i had Trigemial Neuralgia in 2021 and was taking Carbamezapine and Indocin. It went away during the time I am taking. But on the 3rd week i developed severe allergy and it was a horrible experience. I had it for almost 1-1/2 months and i can not sleep becasue it was very itchy all over my body. I have seen an allergy/skin doctor....they even took a part of my skin to test. Came back that it was drug eruption from "Carbamezapin". It slowly went away. My nerve pain goes back and forth. It will go away for few months then came back again. When my husband passed away in June 7 . I developed anxiety, mental and emotional distrubance, stress so my nerve pain came back. I am now taking Gabapentin 300mg 3x a day and Phenytoin 100mg 2x day that were prescribed by the previous neurologist who retired. The nerve pain usualy trigger when I talk loud or longer. Sometimes brushing teeth or washing my face or simply biting hard food. It's always bothering me because the Rx seems not helping me anymore. My neuroligist said that it doesn't seems like TN so she asked me to go to my PCP. She said maybe go see ENT or my dentist., I did but the xray on my nasal is okay and my dentist did take ultra sound of my teeth and it looks okay too. I had one tooth that has been bothering me so i requested him to pull out. It was okay for awhile and the trigger stop. But after few months it came back again. This really is bothering me. I decided to see another Neurologist since the previos one already retired. He said my issue is not TN but "SUNA" and also told me that "You came to the right place. Don't worry I have seen many patients like your issue and I will take care of you" then followed by telling me that only 3 doctors in Oregon are treating this kind of disease and he is one and mentioned the names of the other 2. All 3 of them are from OHSU. Actually he wrote an article about this. Then he prescribed LAMOTRIGENE start with low dosage 25mg for 2 weeks, then 50mg for the next 2 weeks , 75mg for another 2 weeks then 100mg on the last 2 weeks then go back to see him. The reason he start with low dosage because i mentioned that i had allergy on Carbamezapine . He said the new Rx is a good one. I took the Lamotrigene for 2 days. Last night I feel something was crawling all over my scalp. I thought it was an insect but turn out it was like a needle/electric shock all over my scalp. Every time I touch it was very painful. I did not take a shower. Then I took Gabapaentin and Phenytoin before I go to bed and it went away after few hours except the right part of the scalp down to my forehead so I stop and just go to sleep. When I woke up and touched it, It was not so bad but late in the morning it came back. I put ice compress for at least half hour and it went away but came back again. I called my neurologist and sent him email on My Legacy Chart to let him know my concern but with back to back patients he is seeing he might run out of time to respond. I prayed to God before I go to send me to the right doctor that can treat me correctly but i Do not know yet because It' ]s just 3 days. I was excited that maybe this neurologist will find the right way to treat my nerve pain so i can live a better life. I am not so sure if this is because of the new Rx or something else. Usually it only took few seconds and it will go away. This is the first time that it lasted a day. Wonder if anyone else have this kind of issue. How do you shanpoo your hair when you can not even touch your scalp. Please help me and give me some advice on how you manage to handle this trauma.
