HI! MY TWIN SIS HAS HAD SEVERE SWELLING OH HER RIGHT KNUCKLE. IT COMES AND GOES BUT MOST RECENTLY, IT WAS SWOLLEN TO THE POINT OF DISFORMITY!!! VERY HORRIFYING TO SEE AND ALARMING , TO SAY THE LEAST. THIS IS QUITE RECENT.....AND I AM WONDERING IF THE CORTISCONE SHOTS SHE S RECEIVED OF LATE, (AND SHE HAS GOTTEN HER SHARE), BUT RIGHTFULLY SO, COULD HAVE ANYTHING TO DO WITH THIS REACTION???!!!! ALSO, SHE TAKES A FORM OF AMPHEDIMINE SALTS TO TREAT HER ADHD.....ARE THEY KNOWN TO BE FACTORS IN SWELLING OF ANY SORT??? pLEASE ADVISE. THANK YOU. SB
