Hello and thanks for posting,

I can appreciate your concern. I am not aware of these drugs specifically causing hard lumps in the skin. Unfortunately, I can't give you a clear answer on this.

Do ask your GP and/or hospital team to assess this lump, and they can advise you further, as there could be many medical explanations for it.

I hope that you are able to get this health concern addressed soon.

Kind regards,

Vanda
