Worried sick :(

So about 18 months ago I had mycobacterium absessus skin infection and had to get my implant removed and get IV medication through a picc line. I did around 4 months of the IV medication. I never finished the 6 month course bc my husband ended up getting stationed somewhere else. Anyways I am now 29 weeks pregnant and feel some of the symptoms I had when I had the infection. I have tried to tell my midwives and OB but they all say its sciatic pain and not to worry. But I AM WORRIED. IM SO AFRAID :( has anyone gone through something like this?
