I have been in extreme muscle pain for days now, very deep pain almost everywhere. Now today i'm having dihrea (sp?) like sympoms, That feeling in bowls when you know you can't hold it. But all i'm passing is a mucus type substance, that dosen't smell all that great. Sorry for being gross! i have been off my ABX med for two days, to see if it was related to my muscle pain. Been taking about 1000 to 1500 of ceftin a day for little over a month, only symptom, until now, has been just a gradual increase of normal symptoms i usally feel. Any input???? Side effects to report to doc. includes, fatigue, and muscle aches, which we all have already, but my muscle aches have been way more than my normal, and increasing.
