My Tsh is 0.49 t4 15 and t3 normal. But I have started to feel weak in thighs and aching neck and shoulders and tired. Do not undrtstand as when I first started levothyroxine 50 mg felt better but on 88 mgs feeling unwell. My heart is thumping.

88mcg is funny amount. Why not 75mcg? Also are you taking same brand of thyroxine? Some of us can only do well on certain brands. It is recommended to always stick on same brand (once you find one that suits)
If they have not been done ......Suggest you ask GP to check levels of vitamin d, b12, folate and ferratin. These all need to at good (not just average) levels for thyroid hormones (our own or replacement ones) to work in our cells
Aching can be low vitamin D, weak legs could be low B12 or You could be on slightly too high dose, or high because not absorbing due to low vitamins.
Also have you had thyroid antibodies checked? There are two sorts TPO Ab and TG Ab. (Thyroid peroxidase and thyroglobulin) Both need checking, if either, or both are high this means autoimmune thyroid - called Hashimoto's the most common cause in UK of being hypo.
(NHS rarely checks TPO and almost never checks TG. NHS believes it is impossible to have negative TPO and raised TG. It's rare, but not impossible, there are a few members on here that have this.)
Make sure you get the actual figures from tests (including ranges - figures in brackets). You are entitled to copies of your own results. Some surgeries make nominal charge for printing out.
If you have Hashimoto's then you may find adopting 100% gluten free diet can help reduce symptoms, and lower antibodies too.
You do not need to have ANY obvious gut issues, to still have poor nutrient absorption or low stomach acid or gluten intolerance
Best advice is to read as much as you can. Vitamin and minerals levels are very important, but standard NHS thinking, doesn't at the moment seem to recognise this.
You will see, time and time again on here lots of information and advice about importance of good levels of B12, folate, ferritin and vitamin D, low stomach acid, leaky gut and gluten connection to autoimmune Hashimoto's (& Grave's) too.
