I have had an abscess tooth for over a year. I haven't gotten the recommended root canal due to lack of funds. Twice in the past year, my cheek became very swollen, I went to the dentist and got a prescription, which eliminated the infection but never got a follow-up root canal. Since then I developed a small swollen mass on the inside of my gum which was there for about two months, but haven't had any pain in the tooth since then.
On Monday, the mass on my gum went away and my cheek and jaw swelled up. I've been taking Bactrim and Keflex since then. The swelling has gone down some. For the past two days I've had an extremely intense burning and tingling feeling in my left hand up to my elbow. I've been experiencing numbness in my pinky and ring finger, and have had shooting pains up my hand into my elbow. It's also very itchy.
Could this all be related? I need to know if it's worth going to Urgent Care because I don't have insurance.
