Medication

After having an allergic reaction to sulphursalizine, I was placed on oral methotrexate. After about a year I was finding it difficult to keep the 20mg dose down so I was switched to injections. A few days after the fifth injection I collapsed in work with symptoms that were thought to be a mini-stroke. Four months later I was started on Embrel injections and had a similar experience. It is now three months later and I am still experiencing symptoms. Has anyone else had problems like this??
