Thanks for writing in HCM.
From the history which you have given I would suggest the following
1. A complete course of specific drugs namely T Cifran 5oomgms BID, T flagyl
400mgms TID, T rantac
150mgms BID. this should be continued for 14 days.
2. Stop all other drugs immediately.
3. Stop eating outside food. eat only well cooked and hygenic food.
4. Same applies to water. ensure that you drink clean and potable water, preferably boiled.
Repeat a USG of the abdomen. if the liver abscess
is still seen then I would suggest that you take a 5 day course of IV antibiotics. That will give quicker and ensured relief .
If you have any further querry please write back.
