Is Typhoid Infection Associated With Chest Rashes &muscle Pain?

hello, i was diagnosed with typhoid (1:160 1:80) ten days ago and given antibiotics which i've been using faithfully(except one day i took the next tablet after only 6 hours instead of waiting for 12 hours but then compensated with an 18 hour wait for the next tablet)..i finished my antibiotics yesterday but i still feel weak and have joint pains sometimes & muscle pains also. i also hd a rash on the chest and neck this last week.. i just want to know if this is normal..
