Thanks for your query, I have gone through your query.
As far as the
pyogenic granuloma is concerned, it occurs commonly during
pregnancy, but it can also occur secondary to deposits or any irritation.
Regarding the blisters on the lip and reddish gums, it is because of the
herpes virus infection resulting in
herpetic gingivostomatitis.
If i am your treating doctor, I would have suggested surgical removal of the pyogenic granuloma but it has a recurence rate of 2-3%.
For the herpes virus infection, it is a self limiting infection, but you have to get your teeth cleaned once.
Regarding your financial problem, you can get it treated in a educational institute, where they do the treatment under nominal price.
I hope my answer will help you, take care.
