Had a nasty chest cough/sore throat a few weeks ago and got checked out a doctor so I could try and knock out whatever I had before an upcoming tournament. Doctor went ahead and put me on a 10 day antiobiotic. I'm about to finish up the prescription, but just noticed that I started having muscle twitches in my right calf muscle. I had the same thing happen last summer but I always attributed these muscle spasms/twitches to a lower leg injuries I was battling at the time and they eventually went away on their own after a few months. However, I wasn't playing tennis during these months as I was recovering from calf/quad strains. However, these twiches returned this week just as I was finishing up my dose of antiotics. I'm now fairly certain that the twitches I experienced last summer were attributable to an antibiotic I took in the early summer when I had a similar summer cold/sore throat. That aside, I plan on playing in a tournament in a few weeks and was just curious if anyone else has experienced simmilar "muscle twitches" and whether or not these twitches may make me more vulnerable to calf muscle cramping or strains that may affect my ability to play/finish matches.
