Intagesic-MR Tablet Health Feed

I am 28 years old, mom of two kids. Younger one is 11 months old and I am lactating her along with solid foods. I had abortion when my second kid is 5 and half months. From that moment I am feeling severe back pain and my toes and fingers gets swelling while waking up from the bed and I can not able to to fold. I even can not able to keep few steps forward. After sometime, the pain will get reduced by itself and the bone aches remains there for whole days. I realised it whenever I carry my younger one but can not able to hold her for one shot of 10 mins. So consulted few doctors they suggested calcium 1gm, iron, b complex, vitamin d tablets upto the date I last breastfeeding my younger one. I feel little depressed and finally consulted a siddha practitioner and had chooranam for about 30 days. Days went happily but after a month / now the pain is again re-entering in my body. How can I control it with exercise? Shall I take multivitamin gummies available in online shops which has all vitamins a, b, c, d,k, zinc, folic acid and so on? Pls suggest me to get well soon?
