I just finished a round if penicillin for a tooth abscess . Finished about 4 days ago. But am now experiencing severe constipation, upset stomach bordering on nausea, headaches and general fatigue. Can it be side effects from the penicillin? I am 48-year old female with Mulitple Sclerosis, degenerative disc disease and chronic pain . I take multiple medications but I don t typically feel this way.
