In 2007 when I was 18 I developed optic neuritis, which was quickly diagnosed in eye casualty. The symptoms were awful with complete blindness and horrific pain. I made a full recovery and had an MRI scan. The scan was clear and I was told I was in the “low-risk” category for developing MS in the future. Not everyone who has this will go on to develop MS. I was then discharged.
In 2016 I was diagnosed with Crohn’s disease and have been on 50mg of azathioprine ever since, my weight is around 51kg but any higher dose of azathioprine causes my white blood cell count to fall.
In 2017, 10 years on from the optic neuritis episode I developed aching in my right eye socket that would come and go. I knew it wasn’t optinic neuritis again but given my history I had it checked out. I had another MRI scan without contrast which again was normal and I was again discharged. The symptoms still happen on occasion but fairly rare.
Then last week I flew to Lisbon and upon arrival noticed tingling in my right calf. It subsided by the weekend and I flew back on Sunday. But then on Monday I did a huge hike and it returned and been tingling ever since. It’s been 12 years since my optic neuritis episode and I am now 30 years old. The symptoms in my calf are mostly at the back from the calf to the ankle but sometimes I can feel it at the front in the shin too. The tingling is mild and doesn’t impact my walking at all but it just frequently feels “there”. Obviously I’m frightened. What are people’s thoughts?
