I have been struck down yet again by I'm not sure what , I'm 40 and have type 1 since I was 10. I have had this before but not as bad, both my legs very painful now my knees hurt with one slightly swollen.when I first had this I was told it was a virus,this is affecting my whole day to day life including my family around me, iv now had more blood tests which came back clear and have been referred to a ryhmertologist. I'm really struggling to understand what this could be ,not much help from gp or diabetic nurse....has anyone experienced anything like this ,, thanks x
