Welcome to the forum. It is good to know that you are better now and have less pain. You are recovering. When you take medicines, you should keep yourself well hydrated with soups, juice, pure hygienic water so that the medicines work well and the toxicity in your body gets flushed out. If you do not keep yourself well hydrated and are sensitive to the prescribed medicine you may suffer from side-effects.
If you think you are fine, you should re-visit your treating doctor for physical examination, you should be assessed so that if any changes in the prescription has to be made, can be done. Since you are re-covering you may need antioxidants and milder antibiotics or substitutes.
