I recently got a cyst(big lump by earlobe and it went into the gland) behind my ear that swelled up. Dr. Gave me keflex-4 times aday. I have been on it two days and feel sick! I already woke at 5:00 this morning with a panic attack. How do you make the mind stop? My husband has no understanding and thinks I just need to keep moving. I can't at this time. My stomach is all quesy and I feel weak from the meds and probably the cyst. Any advice?
