I have UV and although the diagnosis is confirmed, no cause can be found as to why I,m having really nasty flares roughly once a month, To cut a long story short my Rhuemy who I saw on friday is requesting a blood test within 3hrs of a flare and another one 24hours later, but he also says he,s reffering me to a specialist Gentic testing ? hospital in North London, has anyone had experiance of this and the reason for it , and if anyone has ,did you find it helpfull,I,m getting really exhausted with it all and not really getting anywhere. today my face feels all tingly and I,ve been feeling very tender to the touch at my temple,I don,t know if it,s just a touch of neuralgia,or another symptom. any info anyone. thanks.
