In desperation I called in on our local Citizens Advice Bureau on Thursday and I'm so glad I did. After telling the very kind and helpful gentleman about my problems over the past 6 years with Mercury Pharma Levothyroxine and what I think caused the sticky spots to appear all over my body, he gave me a sheet of paper with information on it about Acacia Rigidula and the problems it can cause match the problems of my son and myself. The link to this information is - blog.priceplow.com/bmpea
The very helpful gentleman also gave me the name and address of a solicitor who may be able to help with some advice.
If anyone needs any more information, please pm me.
Any other information on this problem excipient would be gratefully received.
