Calf Pain after Anti rabies vaccine.

I have taken 3 dose of Anti rabies vaccine (Chiron Behring make) from government Hospital. Day 0,3,7. After the 2nd i have started slight pain in both leg calfs. From another day pain was slightly more on side (which is bearable). After that pain is on same level for long period & now its almost 28 days pain is still present but reduced to some level. I dont get any Fever or whole body pain after vaccination. My problem is that why is this happening. Just one year ago i received 3 dose of anti rabies vaccine of PVRVaccine & without any side effects , I have done after 25 days that are CBC,ESR,CRP,Serum Calcium,uric acid, urine routines . CBC- only WBC count was slight high-11*10^9L ESR-19mm for 1st Hr CRP-4.0 Serum calcium-8.7 mg% Uric acid- 3.8 mg/dl Urine -no abnormal findings. I am worried about is this any neurological issue like GBS,CIDP...etc I don't have any weakness in legs or hands No any numbness Just having Calf pain & some level of fatigue after full day work.
