Yes I strongly advice you to go to the A&E as soon as possible. This needs to be seen by a surgeon. Debridement along with incision and drainage may be required. Also they may consult with the hand surgery service if deep infection, such as involving the tendon sheath or other structures, is suspected. Treatment as soon as possible will prevent further spread of infection and loss of tissue. This is especially so in view of your high risk pregnancy.
