Question: I have been taking Doxycycline, 100mg twice a day for 2 1/2 weeks for a cellulitis in the lower leg of unknown origin. Ultrasounds for DVT were negative, but skin remains mildly sensitive and slightly red. Is there a risk of a particular bacteria developing resistance to the antibiotic by continuing the doxycycline ?

Brief Answer:
not necessarily

Detailed Answer:
Hello and thank you for your question.
There is always a slight risk of resistance when antibiotics are taken not usually this occurs when more is taken than is needed for treating the infection.
If the infection were getting worse then changing the antibiotic might be recommended. However, if it is just slow to clear up, that is pretty typical for cellulitis and a longer course may just be needed to get rid of the infection. Make sure to take some probiotics when you get off the antibiotics to restore the normal bacteria in your gut

my daughter is 16 years old and recently was hospitalized for cellulitis in her leg. She is now having chest pains with fast heart rate as described as feeling it in her throat and her throat tightening. She has also been having leg spams in the same legs as the cellulitis. Any ideas?

Hello, I have had a big edema on my leg after being hurt while playing soccer (december). Things were getting better and the wound had almost completely healed about a month later (january). I then went to a sauna and 2 days later I started having a serious infection at the site of the initial injury. I went to the hospital and got some penicilline. I took one pill and went to bed. The next day I started having some rash and my leg was looking worst. I went back to the hospital and they gave me another antibiotic (Dalacan C). After few days the infection was better but I had rash all over my body. I took a lot of anti-histaminic and things got solved after one week. I now believe that what I got is cellulitis. I now decided to go back to the hospital to test whether I am allergic to penicilline (june) but the results are negative. My question is the following. Is it known whether cellulitis can induce rash all over the body (except head and hands), I mean a different rash than the cellulitis itself? I am 38 years old, 1.93m
