Bump behind the calf, slight localized pain if I press. What to do?

Hello ma'am, thank you for your question, but the situation you describe requires the attention of a physician. In fact, only doctors can provide a diagnosis and I think we need a clear diagnosis before we attempt a treatment option. Otherwise, we risk causing negative effects without the benefits of treatment, as well as causing a delay in addressing your current situation.

I am sorry I cannot help you at this time, the situation you describe is beyond what can be addressed on this platform.

Have a nice day,

Tom Samaha, pharmacist

With pleasure, I wish you a good continuation!
