Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain and explanation of the condition that root pieces will come over the surface which means that you have left over root pieces and the swelling and redness in gums is due to inflammation and the pus discharge clearly indicates that there is infection..
The rubbery white pieces does not seems to be root pieces as the root pieces are not rubbery in consistency and are hard structures..
Tiredness and loss of apetite can be due to
anxiety and pain and it is also possible that there is
septicemia leading to the symptoms whereas spasms in hand are not related to dental problem..
You should consult an Oral Physician and get evaluated and get
x ray of the lower front region done to rule out the exact cause of the infection and pain and get treated accordingly..
As of now you can take anti-inflammatory painkiller like
Ibuprofen for relief..
Hope this information helps..

Thanks and regards..
