He’s got it on both hind feet, this is the worse foot
Just to make things worse I just noticed today that our other pig has a cyst in his ear. He scratched it and made it bleed and partially burst. I’m reluctant to take him to the vet now since they don’t seem to know what they are doing. I’m now stressed and worried about both of them.
Does this guinea pig already have a topic? If so, please do not start a new one! It helps us to have easy access to a guinea pig's medical history. At the very least, you must include a link to any previous topic with a summary of that topic.
The medical forum is almost exclusively used to ask questions concerning problems with individual guinea pigs so a history is extremely important. In the past, we have even suspended the accounts of people who do not follow these guidelines, so please do follow them. The people who are likely to answer your question read every new post in the medical forum so it will not be missed. A very few questions go unanswered if we have nothing to add.
A quick search turned up all my warnings on Guinea Lynx and a pdf on vin that also warns against its use:

Pharmacotherapeutics in Exotic Small Mammals: An Update and a Review by James W. Carpenter, MS, DVM, DACZM (who has published the well-respected Exotic Animal Formulary, with multiple editions). I highlighted some info below:
Inappropriate antibiotic treatment can also result in enteritis and antibiotic-associated clostridial enterotoxemia in rodents, especially when antibiotics with a primary gram-positive spectrum are given. Incidence is higher when agents are given orally. Chinchillas, guinea pigs, and hamsters are most susceptible. Also, direct toxicity from streptomycin and dihydrostreptomycin occurs in gerbils, guinea pigs, hamsters, and mice. Procaine, included in some penicillin preparations, can be toxic to mice and guinea pigs. Guinea pigs and chinchillas are highly susceptible to the ototoxic effects of chloramphenicol and aminoglycosides at dosages above those recommended clinically. Antibiotics implicated in antibiotic associated clostridial enterotoxemia in rodents include:
Guinea pigs: penicillins (including ampicillin, amoxicillin), cefazolin, clindamycin, erythromycin, lincomycin, dihydrostreptomycin, streptomycin, bacitracin, chlortetracycline, oxytetracycline, tetracycline, tylosin.

If you can't switch to another vet, contact this same vet and ask to speak to her directly. I'd say something along the lines of, "For my own peace of mind, since I'm concerned about this particular drug and don't want to take any chances, can you please substitute Baytril? I'll be happy to pay extra for it." If she's any decent vet at all, she'll respect your concerns and make the switch.
I wonder if she is just covering her tracks, badly.
p.s. we have had several new members lose their pets because unknowledgeable vets prescribed this drug.
